This is an album exclusively devoted to Sterling, my beautiful big blue British Shorthair. He loves exploring everything, whether it's indoors or outdoors. Enjoy the pics.
Can you please specify? Which animal? How is it "chewing"? The neck is a very sensitive area for cats. If it's causing any sort of injury whatsoever, please take him/her to an emergency vet immediately. We can't exactly offer any advice until you clarify what the situation is.
