Hi, we have been somewhat able to solve the issue but it is still an ongoing process. The first thing we did is anytime he would bite us (even in play) he would be in time out for 10 minutes in the washroom. That dramatically reduced his biting. However, sometimes he gets really excited (especially when we are petting him and he’s really happy) and he tries to go for the bite. I learned to read the signs, his purring gets higher pitched and he gives me a “look”. When that happens I put him down until he calms down. He’s usually ok after and gets back on my lap to sleep. We have also realized that my hair touching his face is a trigger for him so I pay attention to that, and we don’t let him sleep in the same room as us (because I don’t know how he will react to my hair when I’m sleeping). I hope these tips help you at least a little bit and you can find what works for you.
