The absence of social behaviours could mean that your cats are just tolerating each other.
Cats Protection Behaviour Manager Nicky Trevorrow explains how to recognise feline social groups. It can be very hard to tell with cats as they have not evolved the complex facial muscles to show a wide variety of facial expressions. The absence of social behaviours could mean that your cats are just tolerating each other. If you are regularly seeing any of the negative behaviours, then your Cats are likely to be foes. Recurrent stress-related illnesses, such as cystitis, over-grooming and skin conditions could be the cause. Talk about the change in the behaviour of your cats to your vet. If your vet feels that it is behavioural, then there are a variety of possible causes. The key is to identify the underlying cause for your specific cats. Getting a referral to a qualified behaviourist is the best way to get it sorted out sooner rather than later. Just wishing the cats to get along, or leaving them to ‘sort it out’ is not enough.
