I have used only this type. I think somethimes I should get one a little larger because it seems kitty looks a little cramped. I have had some problems with the bolts coming loose and the top coming off. Kitty still likes it.

Pros: A convenient carrier

Cons: Bolts can come loose

This is a great thing to have when you need to travel with your cat. They may not like it but it will save you a lot of trouble later.

Pros: keeps them inside

Cons: they don't like it

This kennel is easy to assemble and is great for any small pet.

Pros: nice, easy to assemble

Cons: none

If you have to get inside and clean it, the little black knobs are hard to get all 8 of them off. I would like to see snaps or something else.

Pros: Ease of use

Cons: hard to open

this looks like the same as any other case to me.

Pros: i am not sure why this is different

Cons: none
