The 3-3-3 rule for new cats
What's going on
Cats decompress more slowly than dogs, and more invisibly. A dog in shock often looks anxious or shut down in obvious ways. A cat in shock disappears under the bed for two weeks. Both are signs that the animal is doing exactly what they should be doing — protecting themselves while they gather information about their new world.
Three days
Most new cats will hide. Some won't eat for the first 24 hours (call your vet if it goes longer — cats are vulnerable to fatty liver disease fast). Many won't use the litter box where you put it on day one. Many won't make a sound.
What to do: set up a small base camp (one room, food, water, litter box, hiding spot) and respect their hiding. Sit in the room, read a book, ignore them. Don't reach. Don't talk. Be predictable furniture. See fearful cats.
Three weeks
By week three, most cats are coming out, exploring, possibly approaching you. They may start eating in the open. They may start play-stalking your feet. They may meow for the first time. The 'real cat' begins to surface.
What to do: very slowly expand their world. Open the base camp door — don't push them out. Add a wand toy session a day. Drop treats near you. Let them choose contact. If they have other cats or dogs to meet, this is when introductions begin — gently. See cat introductions.
If your cat is still hiding at three weeks — that's still okay. Some cats take three months. We've seen it many times.
Three months
By month three, most cats consider the house theirs. They have a routine. They have favorite napping spots. They have opinions. The cat you adopted has become the cat who lives with you. For many cats, this is when their full affection blooms — the most patient adopters get the most beautiful cats.
When the timeline is longer
Many cats take more than three months to fully come out, especially cats who came from hoarding situations, who lived feral, who lost a former human, or who were deeply unsocialized. Six months, even a year, is normal for some cats. The patience pays.
What to avoid
- Don't try to drag the cat out from under the bed for any reason short of medical emergency.
- Don't introduce other pets or visitors in the first weeks.
- Don't move the litter box without a slow transition.
- Don't take 'no contact' personally. Your cat isn't rejecting you — they're learning safety.
When to ask for help
Concerns we'd want to know about: not eating for 24+ hours, not drinking, not using the litter box for 48+ hours, lethargy that seems beyond normal hiding. Otherwise, ride it out. Reach out to us with questions — we love these stories.
