My pups really do not have much experience with cats.
We did have one get in our fenced in backyard last year. Vivi, the min pin, saw the cat first and went into a true point stance. Piccolo, then went into vicious mode, and I was not sure if the cat was going to be able to make it out alive or not. She had the cat cornered as I was running trying to get hold of Piccolo before a fight broke out. Thankfully, the cat was finally able to jump on top of the fence and get away. Both dogs walked around with their tails straight up afterwards and looked quite proud of their accomplishment of getting rid of that interloper.
