Why does my cat bite me very hard and won't stop when I pet him sometimes
Hi,
I have a 7 month old mainecoon who bites very hard unprompted and when pet will grab your arm and won't let go. I tend to advise any guests to not pet him as he has bitten guests in the past, when he does bite, I put him in a calm, quiet room for him to try and calm down. He doesn't growl or hiss, but he does bite very very hard, fortunately I am the only person he has managed to draw blood from his bites (I see a doctor to prevent infection). I have no idea why this behavioral thing has started and what to do. I play with him and I have a pet sitter whos only job is to play and snuggle him for 1 hour while I am at work. I have captured a video of this biting happening before I pet him, the petting can be anywhere even his head and this will happen. I try to make my arm limp to make it less attractive to bite but also to prevent him from biting harder as he will latch on with his paws and start kicking and biting if I pull my arm back and react. In the video he is also purring so i am pretty confused as to why he might do this and how to prevent it. This also happens when he is pushing himself into my hand to be pet and then i pet him and i get bit.
I got the video so I can replay what is going on, but it is so hard to read my cat as he is unpredictable. He is also neutered if that makes any difference.
Any ideas?
