We have two cats. The oldest boxer doesn't mess with them, the cats rubbed on him and he just sit there starring at them. Meanwhile the 6month old would grab a tennis ball and dropped it on the cats.. It a funny sight. ;D They usually do well, but give them time to work it out. The puppy be little rough at first, because they tried play with it, and they might unintentionally harmed it. Boxer get their name for using their paws a lot. My 3 year old, when he gets excited he will jump on your body, and when he wants attention he will paw me. All 85 pounds of him will jump on me. You have a choice when they are pups to get their ears cropped, me, My first one had hers crops and I love it, my other two doesn't have it crop. It just personal matter, I wish I had cropped my 3 year old, but ah well. It cute when he runs and ears flops. Chicks dig it. 8-)
