Cat behavior
A new cat can hide for several days, but how long matters less than the basics. Worry sooner if your new cat is not eating, drinking, using the litter box, or seems sick.
Hiding is often a normal first-room strategy. The goal is not to drag the cat into family life; it is to make the room predictable and confirm the body is coping.
A new cat under the bed can still be adjusting if food disappears, water is used, and the litter box looks normal. Progress may happen at night before it happens in front of you.
Add distance, choice, and a safer outlet before adding more handling. Shorter sessions, clearer escape routes, and predictable routines often tell you more than one dramatic correction.
Give your cat a safe cave, a clear path to litter, food, and water, and a quiet exit from the hiding spot. Do not block the only hide unless the location is unsafe.
Treat the visible behavior as a clue rather than the whole answer. Track what happened right before it, how much choice your cat had, and how quickly the room returned to normal.
Sit nearby, read, speak softly, toss a treat if your cat is interested, and leave before pressure builds. Reaching under furniture usually teaches the cat that hiding needs to be deeper.
Start by making the scene calmer and safer, then look for the trigger. A cat who feels trapped, sore, or overstimulated will not learn from pressure.
Check food, water, litter, breathing, vomiting, and whether your cat changes hiding spots. These basics tell you more than whether your new cat accepts petting on your schedule.
Get help quickly for bites, escalating fights, redirected aggression, fear that traps one cat, or sudden behavior that does not fit the cat's normal routine.
Call your veterinarian if your new cat stops eating, stops using the litter box, seems weak, breathes oddly, vomits repeatedly, or hides in a way that feels like illness instead of caution.

No. Make the room safer and calmer, then let your cat choose contact. Pulling them out usually slows trust.
