Great for larger cats, particularly those who hate cat carriers!
I am owned by 2 Maine Coon Cats who are one year old but already much bigger than the average sized cat. These are fantastic as the large opening allows you to lift your cat into the carrier without having to try and ram them in a small opening that they definitely do not want to go in!
When you first get the carrier it is important to set it up correctly and make sure that the lid sits in the little clips on the side. It is made from plastic and you need to help it form into the correct shape. If you do this you will have no trouble closing the lid. I also keep mine closed when not in use and this ensures that when I do come to use it, I have no trouble.
The largest Maine Coon is 6.5 Kilos and he fits in fine and I do not worry about the carrier coming apart when I take him to the vets. I just check all the clips are in place and closed before lifting.
I was so happy with the first that I bought a second one and am equally as happy. If you have cats who hate cat carriers then this is definitely worth considering buying.
