I introduced the newest cat to the bastard dog. It did not go well. The german shepherd likes the cat though.

Give it time. Introducing animals takes patience.

Aww poor thing. :( I'm sure the cat and dog will get used to each other eventually

I think the problem is the older cat is a bit too protective of his dogs. So, the bastard dog maybe thinks that the kitten is dangerous. The kitten is overactive and the older cat is disciplining him just like he did with the little cat that disappeared.
