Why does my cat play with their tail?
This behavior is more common for kittens than adult cats, but can happen at any age. Cats play with their tails when there’s lack of stimulation. They’ll be laying around, suddenly see movement, so their predator instincts kick in and they target their tail. It’s honestly adorable to watch. In some cases a cat will attack another cat’s tail. It’s incredibly harmless and there’s nothing to cause alarm, but just like with any behavior keep an eye on it. If you notice that your cat becomes very violent, hissing at their tail, and doing it frequently, you may want to consider taking them to the vet.
