I think this is a great find!  I use it for lots of different things--when I need to separate cats for either aggression or coming into heat.  I also like to roll it outside onto the deck and it allows my cats a safe way to enjoy the summer air.
Nobody complains about being in it...and because it's on casters, it's really easy to relocate it to wherever I want to use it at the time.  I think it's a great value for the price.
