latches become loose.
This type of carrier is more suitable for very small animals like guinea pigs, rabbits etc.
The latches on the top are moulded plastic and become loose with use. The weight of a cat inside makes makes them open and the bottom part swings open and the cat escapes. There is no additional safety measure to ensure this doesn't happen.
Also, it is very small for an adult cat. There is insufficient room to turn around or avoid sitting in any "accident" the cat may have in the carrier. If your cat is reluctant to walk into a carrier, there are very good models for about $25 with both a wire mesh front door and top loading sliding doors as well. Much safer and more comfortable for your cat. I couldn't imagine anyone using a carrier this small for a dog, even the most miniature of dogs. It would be cruel.
