You might assume that sibling cats will get along, but it’s not always the case. Here are some top tips to try if your sibling cats aren’t the best of friends.

While the bond we have with our own brothers and sisters is often strong, cats don’t always have the same close connection with their own family members.

If you have more than one cat from the same litter of kittens, you might assume that they will be best friends for life, but there is no guarantee.

Cats are a solitary species with no in-built need for fellow feline companions and this also extends to sibling relationships.

Even if littermates get on at first, they can often drift apart as they get older, as cats don’t reach social maturity until they are between 18 months and four years old.

If your cat regularly grooms, rubs against or sleeps curled up with their sibling, then this is a sign that they are in the same social group and have a sustained sibling bond. However, if they block or time share (only use them when the other isn’t around) resources such as food, water, beds and litter trays, live in separate areas of the house or get aggressive with each other then they are definitely not a happy family.

The stress related to difficult sibling relationships can even manifest as behavioural problems or even medical issues such as urinary tract issues or skin complaints.

While there is no fix for getting your moggies to be best mates again, there are some simple things you can do to help them live happily under the same roof as each other.

Tips for helping sibling cats get along

If your cats are still not getting along, then arrange a vet check and your vet can recommend a suitably qualified behaviourist who can provide further advice tailored to your own situation.
