I have very "pleasingly plump" cats. I had a pet door which was pretty small. I may try this one, although they don't get to use it too often - must stay in most of the time because of where I live (busy street).

Pros: large enough for larger felines !

Cons: don't know yet

A little to big for the average cat owner, big enough for a small child to sneek in

Pros: you can use it for your dog too

Cons: your dog can use it too

I just installed this door over the weekend and I was surprised how easy it was. I had a previous cat door installed professinally, and I could afford to have this one done too. I borrowed my neighbors power tools and put it in. It took about 1 hour from start to finish. The hardest part was drilling thru the metal door, once I had it cut out it was a breeze. It looks very professional, and now my cats can in & out of the garage with no problem

Pros: Cats can see thru it

Cons: none

love it! my cat is a large and fluffy guy, so this door is great! it's large enough for him to go through, but still our smaller cat can push through also. It's nice because i can have my bedroom door shut at night and still have the cats go in and out!

Pros: Love it!

Cons: nothing
