SportPet Designs Large Pop Open Kennel

I don't know if our cat will like it, but it's worth a try. She has developed very bad toilet habits in her old age, and we want to keep her has long as we can without living in a toilet. I like the quality and the way it pops up to full size easily and folds back into a fairly small flat frisbee shape so it can be stored away easily. It gets big for use, then small again for storage. It has loops to put a seat belt through if you transport your pet in the car. I think it's pretty good quality with great functionality.
