I use it when we go out to adopt out kittens.

Pros: kittens like it lots of play room

Cons: none

We use these cages to recover feral cats in. They are just the right size.

Pros: None

Cons: none

With shelves installed, this cage does provide a fair amount of room for the space it takes up.
The downside of it is that it is virtually impossible to clean the bottom without completely taking it apart - not something you want to do on a daily basis.

Pros: collapsible

Cons: hard to clean

Great for fostering!

Pros: Nice and folds up

Cons: expensive

These are wonderful for keeping kittens safe and out of harms way. Only problem is, they are really hard to clean. The base gets dirty from little feet in water, food and litter boxes, and they track it all over. When cleaning time comes you have to take it apart in order to get the base clean. That's a hassle.

Pros: keeps kittens contained

Cons: difficult to clean
