This may sound crazy but I have a cat that bites when she wants us to know that she's had enough pet time. When she bites it's a soft little tug that just tells us thank you but please no more. After she does that she'll normally just lay down by us & go to sleep. For my Squeak it's a temperament/tolerate thing. I know it's not advice but you may want to check to see if your cat is just trying to say no more please or oooooo I'm going to get you If it's the I'm going to get you I have no idea
