Is it difficult to >gut a cat, or is that considered inappropriate (or
rather;  Just not >nice for people who appreciate clean air)?

Ahh... it may depend on the state you are in, but I believe that here in
California it is a violation of the law to disable a cat.

And it is more than inappropriate to intentionally posion the air that
everyone breathes... including you and your loved ones.

My opinion,
