I actually think your Rot would love them.
And the little dog would have to fend for himself if the kittens are playful
Have a neighbor who has a very well disciplined Pitbull. I would never venture on the guys property where he keeps the dog. But when he lets him out while he is outside, the dog is still scary. But he obeys the guy faithfully to where I have no problem with him. This long winded explain leads up to the day I found out he had some cats. Got along with that dog beautifully.
If you show your dogs that the cats are part of the crew, you shouldn't have a problem.
