I was worried my hind leg amputee cat would not be able to get in and out easily without making a mess. I am very happy to report it is not very messy. She did need a step stool to access it, but once she figured out how to get in and out she is a fan. I like that it has a manual mode, this really helped with teaching her not to be terrified of it. On the down side the weight feature is not the best. Sometimes it says my cat weighs 2 pounds and other times 6, according to the vet she weighs 7-8 pounds. Overall as a litter Box it’s fantastic
