Why does a cat bite its tail and spin around?

Cat biting its tail and spinning around may be caused by boredom or itchiness in the tail.

1. Boredom

Cats are naturally playful, and when they are bored and left alone without their owners, they may bite their tails or chase their tails in circles. This is actually a form of self-entertainment. If a cat cannot get enough companionship and communication from its owner for a long time, it may start to play alone. This is a normal phenomenon, so owners don't need to worry too much.

1. Itchiness in the tail

If a cat frequently bites its tail in circles, it may be due to an infection of parasites or pathogens such as fungi in the tail, which causes severe itching. In severe cases, the cat may even rub its body against the ground or objects. Owners are advised to gently part the cat's tail hair to check for signs of worm feces or ringworm patches, and consult a veterinarian for treatment. At the same time, it is also necessary to regularly deworm the cat in daily life. It is generally recommended to give the cat an internal deworming every three months and an external deworming every month.
