I just had to come back to say that I remembered the cat(a vegetarian too iirc) being so hilarious. I've watched this film several times when I was a kid and I only just realised it was good old dom now.
I think he should do more stuff, he's a funny guy.
I still remember when he was telling Fievel about his family:
"Years ago, I mean. Eight brothers. Ten sisters. Three fathers".
DeLuise was a funny guy; sadly, he died last month after a long successful, if not hilarious, career. His roles in An American Tail, The Secret of NIMH, or All Dogs Go to Heaven won't be forgotten, you can bet on that! (Out of all of these, I'd have to say Tiger and Itchy were my personal faves!)
