This is a good, sturdy and roomy carrier.
We have two of these and the tops are difficult to close up properly once undone. It takes a bit of jiggling about to make them secure again. We just use the front doors now.
Very roomy especially for big cats...our Ragdolls have plenty of space.
I thought this was great to get my cat in and out of. I needed an open top as I have a problem with one hand, so this box was ideal. She also loved going out the side door then jumping in and out using the top. Great idea.
