Cats in their natural environment are solitary creatures. However, it is becoming more common for households to have two or more cats, which can create stress unless managed appropriately.
Some cats are more sociable than others and decide for themselves whether they will tolerate each other. Positive signs of them getting on include nose-to-nose greetings, playing and sleeping together.
Negative signs include blocking each other from entrances or exits, avoiding each other and stress-related behaviour such as over-grooming, urine-spraying or difficulty going to the toilet.
The best way to manage a multi-cat household is to give each animal its own territory, with separate areas for food and water bowls, and their own litter tray. Plug-in diffusers can help by releasing pheromones that mimic calming hormones and promote social bonding.
Ask your vet for advice if you are considering having more than one cat.
