Very cool!!! Looks like you have a very satisfied customer
I also wanted to say that I use that litter with one of my kitties - my Patches, who is a feral that I'm socializing (who is in her own room). That litter smells like air freshener or something!!!!! My husband and I love the smell.
I make quilts all the time,and I MUST say--that is a WONDERFUL invention.I agree with selling some.
You could even contact some foster homes in the area,and make some for them as a "welcome home" gift for new Meowmy and Daddys.
