Wow, how sad. I don’t have cats but do have a dog that drinks from the toilet bowl (the one we don’t use) but to think that I clean it with products like that. Lost my female about six weeks ago, was playing around in the back yard and within 5 minutes was gone. The vet said it was an aneurysm (sp). That was devastating, and my male is so grief striken, that was his girl & his buddy.
