cat door... any recommendations?

Where can i get a simple good cat door??? any place online?

Re: cat door... any recommendations?

I'm in the market for one as well - so we can keep the door to our unfinished basement closed instead of ajar.

I've seen them at Home Depot, Petco and the pet store in the Elwood shopping center.

My problem is that if I go by the weight they list, I need to get a doog door I'm not sure how stingent I should be with following their guidelines. Last thing I want to come home to is Lucy stuck in the door!
