Chattering Their Teeth Isn’t Bad For Them
If you’ve ever heard your cat chattering its teeth when they see a bird outside, don’t be alarmed. It doesn’t mean they have a toothache and they’re not grinding down their teeth. While experts don’t know exactly why cats make the quick, intense sound, they do have theories.
Some believe that cats make this sound out of frustration, because even though they can see the other animal outside, they can’t reach it through the window. Other’s believe that it has to do with their natural instinct to warm up their jaw muscles in preparation to chase their prey.
