In an episode of the adorably informative series “Simon’s Cat Logic“, illustrator Simon Toland and animal behaviorist Nicky Trevorrow explain why cats have such unusual sleeping places, why they often change the place where they sleep, how much cats sleep per day, whether and what are cats saying when they sleep near or next to each other.
Many owners think that if their cats sleep together on the bed that they must be friends. This very much depends on how the cats are sleeping together. For example if the cats are sleeping together with interlocking paws and maybe they’re grooming each other and rubbing against each other, I think it’s safe to say they’re probably friends or in the same social group. However, if you go back and have a look at your cats and you see that actually they are carefully spaced out on the bed, maybe they’re in a crouched position and they’re very carefully just avoiding eye contact with the other cats, it may be that they’re actually tolerating each other or just not in the same social group but there for the valued resource of the owners bed.
