Well, you are going to have to get rid of the cats.
It is possible to get two different kinds of animals to live together in harmony. One thing you can do is teach your dog to “leave” the cats. If you are able to cue Scully to “leave” them, than that alone could solve your problem.
Another option is to do basic training with your dog while a cat is in the room. This can be accomplished by having someone hold the cat, or just have the cat perched somewhere. I would keep Scully on leash for this. Every time he looks at the cat and does not react, tell him “good boy” and reward him. By doing this, you are reinforcing the behavior of him looking at the cat and not trying to eat it. Also, by doing basic obedience, you can have them in the same room without him entirely focused on eating cat.
Giving him some good exercise before doing this training could help as well.
Here is my how to video on teaching your dog the “leave it” command:
I am doing this using two types of treats. I would recommend you start off doing it the same way.
When this is going smoothly you can start to incorporate the “leave it” for the cats.
Thanks for your question!
