This has been such a blessing. I have a 6 year old tabby and a 1 year old Maine coon. With such different sizes of cats it was important that our little guy would be able to fit and feel comfortable using the cat box. As well as our older lady to feel as fresh as possible with another cat in the house. She is very picky with how extremely the cat box is. This keeps it clean all the time with the cat sensor. It makes it easier and less stressful when we go for vacation, and we don't have to depend on anyone else to clean a cat box that is not theirs.
