I apologize if this has been covered, but I searched and couldn't find anything on Oxine and indoor pets. (My cats are strictly indoor and the dog is a house dog, not a yard dog) . I was wondering if anyone uses Oxine for their pets inside? We just started using it for the chickens, but I would love to use it for the cat's water fountains. I clean the thing out regularly but it continues to get slimy. Anyone? Thanks!
