My 2nd one. I already have the smaller green one I bought years ago.  It has had a lot of use. I decided I wanted this one so my feral Gracie can turn around in it plus I can put her food bowl inside the house versus her food freezing outside of it. It’s soooo easy to put together and set up. I had her in a plastic container with a styrofoam insert. This is much better. I plug it in and I don’t have to worry about her. I am registered to deal with feral cats even my animal control guy was impressed. Spoiled kitty.
