Stress in Cats: Signs, Causes and How to Help (Moving, Renovation, New Family Members)

Cats are creatures of territory and routine. Changes that seem minor to us — rearranged furniture, a new sofa, a visitor — can be stressful for a cat. Chronic stress affects health as well as behavior: it's linked to cystitis, over-grooming, digestive upsets and reduced immunity.

Signs of stress

Behavioral signs

• Hiding more than usual, or hiding in new places
• Reduced appetite, or overeating
• Urinating or defecating outside the litter box; urine spraying
• Excessive grooming, sometimes causing bald patches (often on the belly or inner legs)
• Reduced grooming (unkempt coat)
• Increased vocalizing, or unusual quietness
• Aggression toward people or other pets
• Increased scratching
• Clinginess, or avoiding contact
• Sleeping much more, or being restless and unable to settle

Physical signs

• Dilated pupils, flattened ears, tense posture, tail tucked
• Vomiting or diarrhea
• Bladder inflammation (idiopathic cystitis) — straining and frequent urination

Common causes

• Moving house
• Renovation and building work — noise, strange people, unfamiliar smells
• A new baby, partner, roommate or pet
• Conflict with other cats in the household or outside (cats seen through windows)
• Changes in routine — new working hours, holidays
• Visitors, parties, fireworks
• Lack of resources — too few litter boxes, feeding spots, hiding places or high perches
• Boredom and lack of stimulation
• Unpredictable handling or punishment

How to help

Give control and predictability

• Keep routines — feeding, play and bedtimes — as consistent as possible.
• Let your cat choose whether to interact; don't force cuddles.
• Provide hiding places (boxes, covered beds) and high perches in every main room.

Provide enough resources

In multi-cat homes, provide multiple separate food and water stations, litter boxes (one per cat plus one), scratching posts, beds and perches — spread out so no cat can block access.

Play and enrichment

Daily play reduces stress hormones and builds confidence. See why cats need play.

Pheromones and calming aids

Synthetic feline facial pheromone diffusers and sprays may help some cats feel more secure. Evidence is mixed, but they're low risk. Your vet may also suggest calming diets, supplements or, for severe cases, medication.

Moving house

1. Before the move: leave the carrier out and use it as a bed; keep routines normal.
2. On moving day: shut your cat in a quiet, empty room (or at a boarding cattery) with litter, water and a bed, with a sign on the door so movers don't open it.
3. At the new home: set up a safe room first with familiar items — bedding, litter, scratching post — and keep your cat there for a few days.
4. Gradually open up the rest of the home.
5. Spread familiar scent by rubbing a soft cloth on your cat's cheeks and wiping it on furniture and door frames at cat height.
6. Keep outdoor cats indoors for at least 2–4 weeks in a new home, and update their microchip details.

Renovation and building work

• Keep your cat in a quiet room far from the work, with everything they need — or consider boarding during the noisiest days.
• Make sure workers know not to leave doors or windows open.
• Check the room for hazards after work each day (nails, chemicals, gaps in walls and floors).

A new baby

• Make changes (nursery furniture, new routines) gradually, weeks before the baby arrives.
• Play recordings of baby sounds at low volume.
• Let your cat investigate baby items and smells.
• Keep your cat's resources in the same places, and give them attention when the baby is present, so the baby predicts good things.
