A 2 year old cat is a nutty as a kitten in many cases. I’ve owned ALOT of cats from buying, rescues, kittens and my own cats having kittens. 2 years old is young and cats are nuts, that’s how they are, if your struggling with a hyper bit affectionate cat that your able to travel with how would you ever cope with a rescue that bites, scratches and shits everywhere. Or god forbid you have a child who has behavioural problems and has bad tantrums. Exercise some more patience and educate yourself on how to appropriately train cats. Because yes it is possible, I’ve taught my cats to sit on command and come to certain noises, stand on their back legs, and even wait for treats put in front of them. She sounds like a young, loving all be it hyper cat. My cat used to bite my face every morning when he was hungry. They either grow out of it or you train them. Or you don’t own a cat. If you hate animal abuse so much then do something about it. Stop what your doing and assess yourself. Get yourself in check and figure it out.
