Ok so Paco is in LOVE with balls. He tries to carry around a nerf football which is bigger than his head, and much to his dissappointment I have taken it away and hidden it. His other favorite ball is a tennis ball, which also seems to be way too big for him. He will chase cat balls around too if I let him. Is there a good size of ball for him to enjoy, or should I just allow him to have fun with the ones around the house? I worry so that he is going to get hurt!
