When Angel is all snuggled in, either in my lap or next to me on a blanket (or with anyone for that matter) - he does not want to be disturbed! I cannot remember my other being like that or at least not as growly! If he is all comfy, and you try to move him or walk by him and he "thinks" you are going to move him, he will "attempt" ( but won't) to bite! Of course, my instant reaction is to pull back. Are any of your chis like that when they are all "comfy?"
