Why does my cat lick me and then bite?

So, I adopted a 9-month-old cat from owners who had allergies. He adjusted well, but at night, he startled me by charging at me, licking and biting my arm while purring loudly and aggressively. It was quite intense and painful, so I had to push him away. But he kept coming back and wouldn’t stop. I was confused and frustrated, so I had to play with him until he finally calmed down. This happened three times at night.

It sounds like your cat is showing what’s called “play aggression.” Cats often use licking and biting as a way to interact or play, especially if they’re feeling energetic or overstimulated. The purring and licking can be a sign of affection, but when combined with biting, it might just be your cat’s way of trying to engage with you. Try giving him plenty of playtime during the day to help burn off excess energy and consider using toys to redirect his biting behavior.
