Bought this crate/playpen for a kitten in family. Great way for being able to introduce new kitten with existing cat in household.  Old cat can sniff and examine without feeling over whelmed with new furry friend being out and about in his territory. Also, secure place for kitten when she cannot be watched by family members....kittens can sure fit into small spaces. This pen is also great if your cat is not and outdoor cat...just wheel crate outdoors and let them enjoy the fresh air. The Cat Playpen is very sturdy and I would highly recommend.
