My cat is biting
I just wondered if anyone has any knowledge why a cat would do the following. Rub up against someone's leg, do a u turn and bite that person in the back of the leg. Hard enough that it drew the blood. Also...be sitting on the couch on the phone and the cat walk up and bite that same person on the arm and bring blood again. My cat, Chevy, has always been very intimidating until he gets used to you, but we have had a visitor staying with us for about 2 weeks and Chevy doesn't hiss just walks up and bites him for no apparent reason. He's been inside and declawed since about 2 months old and he is know 5 years old. Can anyone give me some help or advice.
