Cat and dogs do not hate each other . .

It is not agression. It is a puppy. . . What I figure you got Enzo at about 8 weeks. Puppies learn bite inhibition from their siblings and mother at 9 weeks. He has not learned it. That is why it recommended for toy breed puppies to stay until 12 weeks. . .but don't worry the cats will teach him. He will want to play and if your cat well let him know when he is too ruff or had enough. And the cat will bop him or headlock him and bite him back. They are biting hard enough to show him that a bite hurts. It is ok. He needs to learn.

I had 4 cats when I got Galen. He was a tiny spitfire. All the wanted to do is play with them. Of course that was not going to happen with all of them. Some were more patient then others. But give your cats places they can retreat to, Cat trees and perches. Also since he is small he is not running around the whole house the cats have other rooms to go in.

Galen used to run around the living room and all the cats would sit on the couch and cat trees and watch him lol my Guildenstern would be the the most patient. They would lay on the couch together and sleep. . .

As long as you give your cats a refuge to go to when they tire of him. You are good. Cats are very smart creatures. . They will all be fine
