i have two gliders: Pepsi and Soda. Pepsi is really quiet and doesnt bite at all, but Soda crabbs a lot, even when he is not touched or moved. Soda also bites a lot, and he doesnt move too much. pepsi jumps everywhere, but soda stays in the same spot as you put him. Yesterday, he got a little bit active, but generally, he doesnt really move too much. is there something wrong with him?
