I like this carrier simply because of the two doors. I have volunteered during spay/neuter clinics and found that carriers of this type are the best to get pets out of (especially if you don't know if the cat is friendly/stressed/angry) and also very good carriers for returning pets to.

Pros: Two access-points

Cons: A bit on the heavy side

These are great for vet appointments. If you have a cat that doesn't want to come out of the carrier at the vets this is the carrier you would want to have!

Pros: None

Cons: none

the top door makes it easier to get pets out,and gives them more air flow

Pros: top door

Cons: none

This is the best carrier I have ever used. It is so easy to load and unload my cats. Every time we go to the vet, he comments on how convenient it is and asks me where I purchased it.
5 star rating!!

Pros: top loading is the best

Cons: none

This is a great idea .I love that if you can't the cat out the front you can get hem out the top. I know i like it for my cats.

Pros: Esay to get your cat out of the cage.

Cons: kind of hard to clean.
