How to Help a Rescue Cat Settle In: The First Weeks

Give a rescue cat one quiet room with food, water, a litter tray, somewhere to hide and somewhere high, then let it come to you. Cats Protection expects a new cat to hide for a few days at most, and says it can take a few weeks before cat and owner feel relaxed.

In short

How long does it take a rescue cat to settle in?

Most rescue cats come out of hiding within a few days and relax over the following few weeks, though shy cats and cats with a rough history can take longer. That is Cats Protection's guidance: a few days of hiding at most for a typical new cat, and a few weeks before cat and owner feel relaxed. You may see the "3-3-3 rule" online (three days, three weeks, three months). It is a rule of thumb from rescue circles rather than charity guidance, but its shape is about right: the cat you meet in week one is not the cat you will have by the end of the first few months.

The signs that a cat is settling are ordinary ones. It eats at mealtimes, uses the tray, sleeps somewhere in the open, grooms itself while you are in the room and comes over to see you when you walk in.

How do I set up a room for a new rescue cat?

Pick a quiet room you can close off, such as a spare bedroom or a study, and put everything the cat needs inside it before collection day. Cats Protection suggests:

Ask the rescue if you can leave a blanket or an old T-shirt with the cat for its last few days there, so the room already smells of something familiar. On the day, put the carrier down in the room, open the door and leave the cat to come out when it is ready. Tipping it out or reaching in to lift it makes the first hour harder for both of you.

Why is my rescue cat hiding?

Most newly adopted cats hide because a new home is a big change, and hiding is how cats cope with change, though a cat that is in pain or unwell can hide too. Cats Protection points out that this happens even with cats that seemed confident at the rescue. Its advice is to leave the cat be: coaxing it out tends to make it hide for longer. Make sure it can reach food, water and the litter tray without crossing open floor, and spend time in the room doing something quiet, like reading, so your presence becomes boring and safe.

If the cat is still hiding all day after a week, that is longer than Cats Protection's "a few days at most", but not unusual for a very shy cat. Keep the routine the same, keep visits calm and ask the rescue what the cat was like in foster care. See your vet if the hiding comes with not eating, not using the tray, or signs of pain. Cats Protection lists hiding more than usual and becoming withdrawn among the signs that a cat may be in pain, which is easy to mistake for nerves.

Why is my new rescue cat not eating?

If your new cat is eating nothing at all, call your vet, because stress and illness can look the same. Eating less than usual is common in the first day or two. Cats Protection says that as long as the cat is eating, drinking and using its litter tray there is no need to worry. For a shy eater, move the bowl closer to where the cat is hiding and leave the room. Feeding the food the rescue used helps too, as does a strong-smelling wet food.

See your vet if your cat stops eating altogether. PDSA advises contacting your vet whenever a cat stops eating, and warns that cats who go without food are at risk of a liver condition called hepatic lipidosis. With a new cat it is hard to tell nerves from illness, so ring the vet or the rescue rather than waiting to see.

How long does it take for a rescue cat to trust you?

There is no fixed time. Some cats are on your lap on the first evening and some take months, and the rescue's notes on the cat are the best guide you will get. What helps is being predictable: feed at the same times, visit the room at the same times and let the cat decide how close to come. Cats Protection's advice for children applies to adults too: keep calm and let the cat come to you.

Play helps once the cat is out of hiding. A wand toy lets it chase something without having to come within arm's reach of a stranger. Cats Protection says play is important for a cat's wellbeing as well as a way to bond. Grooming comes later. If the cat pulls away from a brush or a hand, stop and try again another day.

When can I let my rescue cat outside?

Cats Protection usually advises waiting between three and four weeks before letting a newly adopted cat outside, so it has learned that your house is home. Before the first time out, Cats Protection says a cat should be neutered, microchipped and fully vaccinated, and you should make sure the microchip is registered to you. Let it out just before a meal, when it is hungry and more likely to come back. Some cats should not go out at all: Cats Protection says FIV-positive cats need to be kept indoors or in a secure space such as a catio, and the rescue will tell you if your cat is meant to be indoor-only. Our indoor or outdoor guide covers the choice in more depth.

How do I introduce a rescue cat to my other cat?

Introduce them slowly, by scent first, then sight, then short supervised meetings. Cats Protection and the RSPCA describe the same sequence:

  1. Keep the new cat in its own room with everything it needs, and the resident cat in the rest of the house.
  2. Swap scent. Wipe a cloth gently around one cat's cheeks and give it to the other, or swap their bedding and put it near the food bowls.
  3. Once neither cat reacts to the other's scent, let them see each other through a barrier, such as a glass door or a mesh screen.
  4. Hold short face-to-face meetings with treats and toys, and end them before anyone gets tense.
  5. Give free access only when you see friendly behaviour, such as playing, grooming each other or rubbing against each other.

Give every cat its own resources. Cats Protection's rule is one of everything per cat plus a spare, covering food bowls, litter trays, beds and scratching posts, and put them in different places. It also says it can take anything from a day to many weeks for cats to tolerate each other, and there is no way of knowing in advance. If the rescue said the cat prefers to be the only one, take that seriously. The RSPCA notes that many cats prefer to be the only cat.

How do I introduce a rescue cat to a dog or children?

Keep the dog on a lead and calm for the first meetings, and let the cat choose how close to come. For children, Cats Protection's advice is to keep them calm, let the cat come to them and show them how to stroke gently. Make sure the cat always has an escape route to somewhere high or a room the dog cannot get into. If the rescue has told you the cat has lived with dogs or children before, that is worth more than any general rule.

What should I buy to help a rescue cat settle?

A hiding box or covered bed, somewhere raised to sit and a wand toy make the first weeks easier; a pheromone diffuser is optional. Everything else is on our new cat checklist.

When should I call the vet or the rescue?

Call the vet about anything that could be illness, including behaviour changes that could come from pain, and the rescue about the cat's history, habits and introductions.
