I bought to take my new cat to the vet. He was only 9 lbs at the time so I assumed it would be more than enough for him. Upon bringing him home it literally fell apart and he got loose outside and had to be chased down. I followed the little instructions there were, latched and tightened everything the was to tighten and it still fell apart. And even when the 2 halves stay together the door never stays in place, complete waste of money!
