I'm handicapped and use a walker, and have found it this mat to be much too thin to stay flat. I found myself tripping over it frequently
LOVE IT! It captures all the litter from the paws and yet is easy on the human tootsies too!
Wonderful at catching flying litter and keeping the litter box area looking a lot neater, but unfortunately the size that would have worked perfectly for my kitty is in-between the large and extra-large.
Exceeded expectations and I'm not easy to please.
