Almighty god! This is horrible!
How can a person do something like that? I myself have a lovely kitty and I love her and cannot imagine my life without her!
But recently she rubbed against my leg and then bitten me, which was really weird. I started looking on the internet about cats rubbing then biting, and found out this article describing cats behavior (
https://kittycattree.com/why-do-cats-rub-against-you-then-bite/)
It was really helpful though and I think if you want to know more about your kitty cat's behavior you can look it up too!
Hope it helps.
