How to introduce a new cat to other pets

It’s wonderful for a pet to have the companionship of another animal (even if some pets might not think so at first). But patience and time are the keys to successful introductions.

Some cats may bond quickly, others may take time to become snuggle buddies (or to simply tolerate each other!). The introduction can take several days (for bold little kitties) to several months (for adult prima donnas). Don’t risk an all-out fight by rushing things.

How to introduce a new cat to other cats

First impressions count, so take things slowly. Allow your cats to smell and hear each other before seeing each other. Let your existing cat have a sniff of a blanket or toy used by the other cat.
Keep your new cat in a separate room for the first few days or even weeks. This will allow both cats to acclimatise to each others scents and sounds before having a face-to-face meeting.
Consider feeding the cats either side of the door, starting out with their bowls placed further away from the door and gradually moving them closer until both cats are comfortable eating either side of the door.
Be sure to spend lots of time with your existing cat so that he knows he is still special. Reassuring pats, fun games and tasty treats go a long way.
Once there are no signs of growling or hissing, it’s time to let the cats meet! Open the door just enough so that the cats can see each other. All being well, you may at this point be able to open the door fully to let your cats mingle. But make sure you allow plenty of escape options and hidey spots so that either cat can take some time out if needed.
Most cats prefer their own litter tray so allow one for each cat, as well as separate food and water bowls.
Watch for signs of stress - eating food quickly then vomiting, excessive grooming, sleeping and/or drinking are signs that your cat isn’t happy. Spraying, toileting outside the litter tray and hiding are also associated with anxiety and stress. If either cat is excessively stressed, comfort them and go back to separating them, taking things slowly.

How to introduce cats and dogs

The same principles apply, but be extra mindful as a new puddy tat can be a very exciting prospect to a dog!

Consider crating your dog and allowing your cat to investigate and have a sniff is a great first step to help your cat get used to your dog and to ensure the safety of your furry family members.
Making a ‘cat zone’ and a ‘dog zone’ in your home using a baby gate to cordon off separate areas is also a good idea. This will allow your pets to slowly get used to each other before meeting face to face.
Ensure your dog is leashed when first meeting your cat face to face, and ensure your cat has lots of escape options and safe spots where he can run, jump to or hide if he needs to.
This process may take days or even weeks before you can comfortably allow your dog and cat to mingle freely. But far better to take it slow and steady rather than risk an unpleasant encounter.
Make sure your cat’s litter box is not accessible to your dog. Cats value their privacy when pooping, thank you very much! And your dog might mistake the contents of the litter tray for a tasty treat (ew!). Baby gates are good for this purpose.
Don’t leave your pets unsupervised unless you are sure they are getting on. If you need to go out during the early settling-in days, it’s best to keep pets separated until you are certain that it won’t end in a tooth and claw war.
