Get the cat his own drum set. Actually, My cat can be a vindictive little F@#$%*@ too. Whenever he sends me a signal of his displeasure, I soak the area with nature's miracle. It breaks down the bio burden and kills the smell permanently. Critters tend to return to the scene of the crime.
True story, I was practicing and stopped for a moment while sitting at the kit to talk a phone call. While chatting, with my foot on a DW 5000 Pedal, a Pearl MCX 22 inch Bass drum, Zildjian A Custom, my cat stuck his head in the port hole to see what's inside.
Now I ask you, what would you have done in my place. Frankly, I didn't see any other options.
The details of my kit have nothing to do with the story. This is a very funny thread BTW.
