the only two cariers i like are these and the collapsable ones. These give you two ways to load and two ways to clean. THats why i like this kind.

Pros: cheap, easy to use and clean

Cons: none

This is a great pet carrier! My cat gets stressed out when we have to take him to the vet, but at least we don't have to try and push him in through the front door (which doesn't work!) - we use the top loader to place him inside, and it makes it so much easier! Also, when we get to the vet, I can open the top and pet him through the opening... all in all this is a great carrier! We haven't had to use it on a plane yet... but it's nice to know that we could if we needed to. We actually took him to the vet in this yesterday, and now it's sitting in the entry way and he's jumped in a few times and even took a nap in it... I always put something soft in there for him to lay on, and usually cover it with a towel when we're in the car so he doesn't freak out looking through the (open) top. Highly recommended :).

Pros: easy access doors, airplane approved

Cons: minor - but I wish the carrying handle was sturdier/padded/nicer

This brand is always reliable; I own a couple of their carriers & like them. Having a door on top of the carrier is really helpful. Before getting this carrier, I would sometimes have to stand one of the other carriers on its side with the door open, & then lower the cat into it, which wasn't always easy. This is so much better!

Pros: top door as well as front door

Cons: none

This is just about the best carrier I have ever bought for my cats. It has a top and a front door so they can see around, and I cannot get one of my cats out of the carrier through the front door, so the top door is perfect, and the cats do not get claustrophobic either. It is durable, and both cats can fit inside to go to the vet. I would suggest from experience getting the jumbo version of this if you want to carry 2 cats together.

Pros: roomy, accessible, durable, two doors smart idea, easy to clean, I like the colors available

Cons: $$$$

I like this carrier. It is spacious enough for the cat to be comfortable and has lots of open space for ventilation.

Pros: spacious, well ventilated

Cons: ?
