Answer
When you say Pippa is getting "aggressive", I need to know exactly what she's doing to the cat.
So when you pull her away, exactly what is happening?

Usually cats rule so I'm curious as to what's going on.

I have two cockers and a cat and they'll bug her a bit but when she pulls out her Clint Eastwood stare they back off.
