Why Is My Cat Hiding
Hiding is a cat's coping tool. Sometimes it is completely normal. Sometimes it is a signal. The difference is in the pattern.

Normal reasons cats hide
A new home, visitors, loud noises, a new pet or baby, or furniture moved around can all send a cat under the bed. This is normal. Cats are small predators that are also prey for larger animals, so retreating to a safe spot is their first instinct when the world changes. Most cats come out on their own once things feel normal again, often within hours to a few days.
Help the cat feel safe

Give the cat places to hide that you approve of: a cardboard box with an entrance cut in it, a high perch, or a quiet room with food, water, and a litter box. Why approved hiding spots help: a cat that has a safe base explores sooner than a cat that feels cornered. Keep feeding times and routines the same. Play with the cat daily, in short sessions, to build confidence. Never drag a cat out of hiding. Let it come out on its own terms, and reward it calmly when it does.
New home? Give it a week
A cat in a new home often hides for the first few days, eats at night, and explores while the house is quiet. Start the cat in one room with everything it needs, then open more rooms over days, not hours. Why one room works: a whole house is too much new territory at once. A single room becomes home base first, and the rest follows.
When hiding is a warning sign
See a veterinarian promptly if hiding starts suddenly and comes with any of these: not eating or drinking, sleeping far more than usual, avoiding the litter box or changes in litter habits, or any sign of pain such as limping or crying when touched. This is the important part of this guide: cats often hide illness. A cat that suddenly hides and stops eating is not being moody. It needs a veterinarian, not more time alone. This guide cannot diagnose anything, and a sudden behavior change deserves a vet visit, not a new training method.
