Buddy has been bitting and we don't play with him with our hands. He has 2 toy mice and another on a stretchy string that broke. He also has the wand that my mom gave me. How do I stop him from bitting. He drew alittle blood (like not even a drop) today. I tried the making it uncomfertable for him thing but it only worked alittle. Should I increase his play time? How should I ground him for bitting? Should I do no petting type grounding or put in his cage for 2 min since he is 2 months old
