When my boyfriend and I do indoor exercises (push-ups, yoga, ect.) and they involve us being on the floor our cat lunges at our wrists, hands, and arms. He does not normally bite that often, if he does we touch his nose and say NO and that usually stops him. Sometimes he doesn't care that we are exercising, but when he does care, it is impossible to get him to stop his repeated attacks unless we use half a spray bottle of water on him. Any ideas about whats going on?
