My cats and I all love this mat.  LOL, at first they didn't but once they got used to it, they sleep on it all the time.  I purchased white (which was so hard to find) and haven't had any issues with dirt, stains or discoloration.  It's under a covered area on the lanai, therefore, I cannot comment on how it would hold up in exposed weather.  It's a nice addition to the look I wanted to create.  Thanks Wayfair.
