Cat Stress Signs: Recognising Stress During Boarding

A boarding stay introduces a cat to an unfamiliar environment, different people, new sounds and smells, and a change in its normal routine.

Some cats adapt quickly. Others remain cautious for longer or need additional support before they begin eating, exploring and interacting normally. A cat's response can also vary from one stay to the next.

For cattery staff, the aim is not to label every quiet or hiding cat as stressed. It is to understand what is normal for that individual cat, notice meaningful changes and create an environment in which the cat has as much security and choice as possible.

Why can boarding be stressful for cats?

Cats generally feel most secure when their surroundings are familiar and predictable.

A cattery stay may involve several changes at once:

A journey in a carrier.
Separation from familiar people and animals.
A new sleeping area.
Different sounds and smells.
Awareness of unfamiliar cats.
New staff entering the cat's space.
Changes to feeding, cleaning and interaction routines.

This does not mean that boarding is inherently harmful or that every cat will find it distressing. Many cats settle well in a properly managed cattery, particularly when their usual routines and preferences are respected.

However, individual responses differ. Cats Protection notes that some cats cope well with cattery stays while others may be more comfortable remaining at home with a trusted carer. It recommends spacious accommodation, hiding places, separation from unfamiliar cats and allowing cats to approach staff rather than forcing interaction.

Start by learning what is normal for the cat

The most useful information about a boarding cat often comes from its owner.

Before the stay begins, the cattery should collect enough information to understand the cat's normal habits and temperament.

Useful questions include:

Is the cat normally confident, cautious or shy?
Does it usually approach unfamiliar people?
Where does it prefer to sleep or hide?
How much does it normally eat?
Does it prefer wet food, dry food or a combination?
Does it usually eat immediately or return to food gradually?
What are its normal drinking and litter-tray habits?
Does it enjoy being stroked or handled?
Does it prefer play, quiet company or being left alone?
Has it stayed in a cattery before?
How did it behave during previous stays?
Does it have any health conditions, medication or mobility needs?
Are there particular sounds, movements or forms of handling that it dislikes?

This information provides a baseline against which staff can assess the cat during its stay.

Hiding, for example, is normal behaviour for many cats. One cat may routinely sleep inside a covered bed for most of the day, while another normally greets everyone entering the room. Remaining hidden may therefore mean something different for each animal.

The question is not simply:

Is this cat hiding?

It is:

Is this cat behaving differently from what we would reasonably expect for this individual?

Common cat stress signs during boarding

Cats can be subtle when they are uncomfortable, anxious or unwell. Changes may appear in their behaviour, appetite, grooming, posture or toileting.

No single sign proves that stress is the cause. Pain, illness and other physical problems can produce many of the same changes.

Staff should therefore consider the whole picture rather than diagnosing stress from one behaviour.

Changes in hiding and interaction

A cat that is struggling to settle may:

Hide more than its owner described as normal.
Remain withdrawn for an extended period.
Avoid people it previously approached.
Stop showing interest in play or interaction.
Become unusually restless or unable to settle.
React defensively when approached.
Hiss, growl, swat or attempt to escape.
Become less tolerant of handling.

Hiding itself is not necessarily a problem. It is an important coping behaviour that allows a cat to feel protected.

Cats Protection advises that a cat hiding more than usual may be stressed, anxious or unwell. It also recommends leaving a hiding cat in its safe space rather than repeatedly trying to coax it out, as forced attention may increase anxiety.

Changes in eating and drinking

Possible signs of concern include:

Eating significantly less than normal.
Refusing food.
Eating only when the cattery is quiet.
Drinking substantially more or less than expected.
Approaching food but appearing unable or unwilling to eat.
Dropping food or showing discomfort while eating.
Vomiting after meals.

A reduced appetite may occur while a cat adjusts to unfamiliar surroundings, but it can also be associated with pain or illness.

The cat's normal feeding habits are important here. An owner may explain that the cat rarely eats while people are present and normally returns to its food overnight. That context helps staff distinguish an established habit from a new behavioural change.

Changes in toileting

Staff should monitor:

Whether urine and faeces are present.
How frequently the cat uses the litter tray.
Changes in the amount or appearance of urine or faeces.
Diarrhoea or constipation.
Straining or repeated visits to the tray.
Toileting outside the litter tray.
A cat appearing reluctant to enter or remain in the tray.

Changes in toileting may be linked to the environment, litter preference, stress, pain or illness. They should be recorded and assessed alongside other observations.

Changes in grooming and physical presentation

A cat experiencing discomfort may:

Groom much more than usual.
Stop grooming normally.
Develop an untidy or greasy-looking coat.
Lick or bite one area repeatedly.
Remain in a tense or crouched position.
Keep its ears flattened or turned sideways.
Hold its body tightly against the floor.
Show persistently enlarged pupils.
Reduce its normal movement or activity.

Body language must be interpreted in context. Wide pupils, for example, may reflect fear, excitement, lighting conditions or another physical cause.

Changes in vocalisation

Some cats become unusually quiet, while others vocalise more frequently.

Possible changes include:

Repeated meowing.
Yowling.
Growling.
Hissing.
Calling during the night.
No longer vocalising in the way the owner described as normal.

Again, the change from the individual cat's baseline is usually more informative than the behaviour alone.

Look for changes and patterns, not isolated behaviours

A single observation provides limited information.

A cat that hides on its first afternoon may simply be adjusting to a new environment. A cat that hides continuously, eats progressively less, stops grooming and produces no urine requires much closer attention.

Useful monitoring looks for:

Several changes occurring together.
Behaviour becoming more pronounced.
A lack of gradual improvement.
A sudden change after the cat initially appeared settled.
Differences between the current stay and previous stays.
Signs that may indicate pain or illness rather than stress alone.

Staff observations should be factual.

Instead of writing:

Milo was very stressed today.

Record what was actually seen:

Milo remained inside his covered bed during both morning checks. He ate approximately one quarter of his breakfast overnight, compared with the full portion reported as normal by the owner. Urine was present in the litter tray. He hissed when the unit door was opened, so no handling was attempted.

This creates a useful record for the next staff member, the owner and, where necessary, the cat's veterinarian.

It also prevents subjective labels such as “aggressive”, “difficult” or “unfriendly” from replacing meaningful observations.

How to reduce cat stress in a cattery

A good cattery environment cannot guarantee that every cat will feel relaxed immediately. It can, however, remove many avoidable sources of stress and give each cat appropriate choices.

Provide a secure hiding place

Every boarding cat should have somewhere it can retreat from view.

Suitable options may include:

A covered bed.
An igloo-style bed.
A cardboard box.
The cat's open carrier.
A purpose-built enclosed shelf or compartment.

The hiding place should allow staff to monitor the cat without repeatedly disturbing or removing it.

Licensed catteries in England must provide a hiding place and an area where a cat can avoid seeing people and other cats if it chooses.

Hiding should not be treated as a behaviour that staff must stop. The ability to withdraw can help a cat feel sufficiently secure to begin observing and exploring its environment.

Provide elevated resting areas

Many cats feel safer when they can rest above floor level and observe their surroundings.

Elevated shelves should be:

Stable.
Easy for the individual cat to reach.
Large enough for comfortable resting.
Positioned away from food, water and litter contamination.
Adapted for kittens, older cats or cats with restricted mobility.

A cat should not have to choose between hiding and elevation. Ideally, its accommodation provides both.

Feline environmental guidance identifies access to safe resting places and vertical space as important elements of a secure environment.

Reduce visual exposure to unfamiliar cats

Cats from different households should not be forced into direct interaction or continuous visual contact.

Solid barriers, careful unit design and appropriate positioning can prevent cats from staring at one another across accommodation areas.

A cat should be able to move around its unit without always being visible to:

Cats in neighbouring units.
People passing through the cattery.
Dogs or other animals.
Staff carrying out unrelated tasks.

In England, cats from different households must never share a unit. Cats from the same household may share only with written owner consent, continued monitoring and authority to separate them if problems arise.

Separate key resources

Food, water, sleeping areas and litter trays should not all be grouped together.

Cats generally benefit from being able to eat, drink, rest and toilet in distinct areas. England's boarding guidance requires food and water to be kept apart and both to be separated from the litter tray.

Where cats from the same household share a unit, provide enough resources to reduce competition. Each cat should be able to eat, drink, rest and use a litter tray without being blocked by the other.

Cats that live peacefully together at home may behave differently in an unfamiliar, confined environment. Sharing arrangements should therefore be monitored throughout the stay.

Maintain familiar food and routines

Where practical, follow the owner's instructions about:

Food brand and type.
Portion size.
Feeding times.
Number of meals.
Treats.
Medication.
Normal methods of presenting food.

Changing both the environment and the food at the same time can make settling more difficult and may also cause digestive problems.

Familiar bedding or another safe item carrying the scent of home may help some cats. Any item brought into the cattery should be suitable for cleaning procedures and checked for safety.

Control noise and disruption

A cattery should protect cats from excessive or continuous noise.

Potential stressors include:

Dogs barking nearby.
Doors slamming.
Loud music.
Cleaning equipment.
Staff calling across the room.
Repeated entry into the unit.
Unnecessary movement around accommodation areas.

Complete silence is neither practical nor necessary. The aim is a calm, predictable environment without sudden or sustained disturbance.

Cleaning and care tasks should follow a consistent routine where possible so that cats can begin to anticipate what happens during the day.

Let the cat choose whether to interact

Some cats seek human attention soon after arrival. Others prefer staff to complete essential care calmly and leave them undisturbed.

Staff should:

Approach slowly.
Avoid staring directly at the cat.
Use quiet voices.
Allow the cat to initiate contact.
Avoid reaching into a hiding place.
Stop when the cat shows discomfort.
Never punish defensive behaviour.
Never force handling simply to make the cat appear sociable.

England's statutory guidance states that interactions must be appropriate to the individual cat and that a cat must never be forced to interact with people.

Hissing, growling or swatting should be understood as communication. The cat is indicating that it feels threatened, uncomfortable or needs more distance.

Offer appropriate enrichment

Enrichment should suit the individual rather than being applied identically to every cat.

Options may include:

Scratching surfaces.
Safe toys.
Food-based enrichment where appropriate.
Short play sessions.
Opportunities to climb.
Objects carrying familiar scents.
Calm human company.

A highly playful young cat may benefit from several interactive sessions. A cautious older cat may find repeated attempts at play intrusive.

Enrichment should provide choice. It should not become another demand placed on a cat that is trying to withdraw.

Monitor appetite carefully

Food intake is one of the most important daily observations in a cattery.

Record what was offered and approximately how much was eaten. Avoid entries such as “fed” when the important information is whether the cat actually ate.

If a cat eats less than expected:

Check the owner's description of its normal habits.
Confirm that the correct food and portion were supplied.
Consider whether the cat prefers eating in privacy.
Check water intake, toileting and behaviour.
Look for vomiting, pain or other signs of illness.
Follow the cattery's agreed veterinary escalation procedure.

Do not assume that appetite loss is caused by stress. International Cat Care states that reduced appetite may indicate underlying illness or pain requiring veterinary attention, although stress can also reduce food intake.

The 48-hour requirement in England

For licensed catteries in England, statutory guidance states that veterinary advice must be sought if a cat has had no appetite for longer than 48 hours.

It also states that advice must be sought sooner where there are specific concerns or known health problems. Water intake must be monitored, with veterinary advice obtained if a cat is not drinking or is drinking excessively.

This is an England-specific regulatory threshold. It should not be presented as a universal rule that tells every cattery in every country exactly when a cat requires attention.

A vulnerable cat, a cat showing other symptoms or a sudden and significant change may require advice much earlier.

Know when to escalate a concern

Each cattery should maintain a written process agreed with its veterinarian.

The process should explain what staff should do when they observe:

Complete refusal of food.
A marked reduction in food intake.
Failure to drink or excessive drinking.
Vomiting or diarrhoea.
Straining or abnormal urination.
Significant or sudden behavioural change.
Signs of pain.
Breathing difficulties.
Severe or escalating agitation.
Unusual lethargy or weakness.
A deterioration in a known medical condition.
Conflict between cats sharing a unit.

It should also explain:

Who makes the decision to contact the veterinarian.
Which veterinary practice should be contacted.
When the owner or emergency contact is informed.
How the advice received is recorded.
How information is handed over between staff.
What happens outside normal veterinary hours.

Staff should not delay seeking advice because a behaviour might be stress-related. Stress and illness are not mutually exclusive, and cattery staff are not expected to diagnose the cause themselves.

Record observations consistently

Good records allow the cattery to identify change over time.

Daily observations may include:

Food offered and eaten.
Water intake.
Urine and faeces.
Vomiting or diarrhoea.
Grooming.
Activity.
Interaction with staff.
Use of hiding and elevated spaces.
Medication administered.
Behavioural changes.
Actions taken.
Veterinary or owner communications.

England's statutory guidance requires the behaviour of every boarding cat to be monitored daily. Changes associated with suffering, stress, fear, aggression or anxiety must be recorded and acted upon. It also requires food and water intake, urine, faeces, signs of illness and abnormal behaviour to be monitored.

Records should be clear enough that a staff member beginning a new shift can understand what has changed without relying on memory or a verbal handover.

Learn from each boarding stay

The end of a stay is an opportunity to improve the next one.

Tell the owner:

How quickly the cat appeared to settle.
Where it preferred to rest.
Whether it ate normally.
When it was most comfortable eating.
How it used the litter tray.
Whether it sought or avoided interaction.
Which forms of enrichment it used.
What appeared to help it settle.
Whether any concerns arose.

Update the cat's profile with useful information for future stays.

For example:

Preferred the covered shelf and ate mainly after the cattery became quiet in the evening. Accepted gentle interaction from day three but did not enjoy being approached while inside the bed.

That is much more valuable next time than a general note saying:

Nervous cat.

For some cats, small adjustments can make future stays considerably easier. For others, repeated difficulty settling may suggest that care in their own home would be more suitable.

A calm cattery starts with individual care

Recognising cat stress signs is not about applying the same checklist or deadline to every boarding cat.

It begins with understanding what is normal for the individual. Staff can then monitor changes in appetite, toileting, grooming, posture, activity and interaction while providing hiding places, elevated areas, familiar routines and freedom from forced contact.

Most importantly, possible stress should never be used to explain away signs of pain or illness. Clear observations and an agreed veterinary escalation process protect the cat far better than trying to diagnose the cause from behaviour alone.

The Kennel Manager helps catteries collect behavioural, dietary and medical information before arrival and maintain consistent daily observations throughout each stay. This gives every staff member access to the same baseline and care history without asking software to diagnose what those observations mean.
