Chattering Teeth
Do you hear your cat chatter their teeth if there’s a bird outside? It’s not because they’re grinding them or experiencing a toothache. No one knows why they do it, but they could be frustrated because they see that bird but can’t attack it.
Butt in the Face
Cats enjoy lifting their tails and showing you their backsides. It’s not fun for the human, but it’s actually a compliment. As they lift the tail and stick their booty in your face, it shows trust and affection. They’re just being friendly!
