Hey guys going on the 3rd year with the cat. it all looks good but last year i was cleaning and like an idiot it was stil a little warm and i brushed it with a paint brush and then i hit it with a vaccum and i hit the cat with the end of my vaccum to hard and knocked this piece off. i mean it still works but just wondering if i should get another one on hand to have in case i need to swap it out if it gets worse. Any of your guy's cats look like this?
