I did, many times. But there were alot of other things that are fixed now could have been causing the problem, so it was hard for anyone to put their finger on just the cat. EXCEPT I'm pretty sure I remember BIO months ago said "I bet months from now when your done fixing all this crap you're just going to have a clogged cat, and then I'm going to laugh at you". Guess who was rightBut whatever, all the other things needed to be fixed at some point anyway so I don't mind.
