My Yorky Brady is 3 and he has been visiting my grandson's tiger cat since he was born (the cat was about 5 at the time and is now 8). Brady keeps barking at the cat and chasing it and it is so frustrating because we only visit my grandson and his parents twice a year. I think the cat teases him because he'll try to walk by Brady while he is sleeping but Brady immediately chases him. The cat has his claws so I am afraid Brady will get hurt. Does anyone have any suggestions as I am getting desperate?
