There are many reasons why cats may become angry and chase and bite people, and the specific reasons may vary from individual cats to others. Some possible reasons include: Cat Feels Threatened or Frightened: When a cat feels threatened or frightened, it may chase and bite people to protect itself. This reaction is natural and common in wild animals. Cat Doesn't Get Enough Social Interaction or Stimulation: If your cat doesn't get enough social interaction or stimulation, it may become agitated and start chasing and biting. This behavior may be your cat's way of seeking attention. Endocrine disorders in cats: Endocrine disorders may cause abnormal behavior in cats, including chasing and biting.
If you notice your cat exhibiting this behavior, it is recommended that you take it to the veterinarian. Cat Playing: Sometimes, cats may play by chasing and biting people. This behavior usually does not cause serious harm to humans, but if you do not want to be bitten, it is recommended that you provide your cat with enough toys and activities to satisfy its play needs. If your cat frequently chases and bites people, it is recommended that you seek professional help.
