I have 2 cats, from day one Mandy chased only one cat, the one that ran away, the other cat she never chased because she never ran.

I agree that cats should have a safe place to go to get away from the puppy. I had baby gate up infront of my bedroom door the cats could jump over it and it was a safe place from the puppy. Puppy was not allowed to chase the cat. As the puppy has gotten older and the cat is less worried about the puppy, there is no more chasing in my house.
