This is the 2nd cage of this type that I have purchased.  I particularly like the 4 large doors that open and lock independently of one another.  The design of the doors is perfect for getting to food and litter box.  The opening is large enough to get a scratching post or a large cat cube bed in and out of the cage. (I only use 2 of the shelves provided.)  The cage is perfect for housing a momma and kittens during the nursing weeks, a new cat for the acclimation period in a home or a feral/community cat during a relocation acclimation period. (I would not recommend it for a cat to live in permanently, however...if you are going on vacation and have a cat service coming in to feed, it keeps the cat safe from escaping past the stranger out the door.  Best assembled by 2 people with some zip ties handy.
