Quick answer

Hiding is a normal cat coping strategy, but sudden, repeated, or prolonged hiding deserves attention, especially with appetite change, litter box changes, or pain signs.

What it looks like

The cat stays under furniture, in closets, behind appliances, or in high secluded spots. The key question is whether this is normal for that cat or a sudden change.

  • Avoiding normal social areas
  • Staying hidden during usual meal or play times
  • Low body posture when emerging
  • Retreating from touch

Common causes

Cats hide after environmental change, new pets, visitors, loud noise, conflict, illness, pain, or litter box stress.

  • Recent move or room change
  • New baby, pet, or visitor
  • Fireworks or construction
  • Pain, nausea, urinary discomfort, or fever

What to do now

Make hiding safe instead of forcing the cat out. Place food, water, and litter access nearby, lower household pressure, and track eating, drinking, urination, and movement.

  • Do not drag the cat out
  • Create a quiet base room
  • Monitor appetite and litter box
  • Use calm predictable routines

When to get help

Call a vet if hiding is sudden, lasts more than a day with reduced eating, appears with vomiting or litter box strain, or follows a possible injury.
