Cats hide when stressed or unwell. Sudden hiding with reduced eating often signals illness — cats mask pain until they withdraw.
Stress hiding
New pets, visitors, or building work trigger retreat.
Illness hiding
Kidney disease, pain, and fever cause withdrawal.
Action
Offer quiet safe spaces but monitor appetite and litter use.
