Sorry to hear that, I feel for you. Didn't even know it was a thing until I had to research what was going on with mine. But to keep things semi on-topic, I try to keep the nice expensive sets out of the reach of the cats, but any time I rotate stock or clean the shelves, I will find one of the fuzzballs curled up in the plastic tub of primes like they were all for him. I mean wtf right? I know when these come in I'll be putting them behind glass. I haven't lost any TFs to cat-nibbling yet but with all those portruding parts I'd rather not tempt them. -Kronatron.
