Mount the cat and proplem solved. My brother has one. That thing gets in or on everything. Heck my dog chased it in the house today it jumped in the toliet. Good thing i had just cleaned the dam thing. LOL I have caught it trying to get my fish out of the tank. If it was me and the cat got on or messed with amount a good kick or toss it off will tell it to stop. Now i do not mean beat the crap out of it just toss it off gently.
