Voted one of Cat Fancy Magazine's Best! Here is what a School of Veterinary Medicine representative has said about Joybies Piddle Pants(TM) ! "Cats aren't particularly fond of wearing Piddle Pants at first, but I highly recommend them over the need to clean furniture or carpeting frequently, or to put an otherwise happy cat to sleep. On the positive side, cats seemed to become accustomed to the pants relatively quickly.These well made overalls can be washed and line dried" . Recommended by the Feline Behaviour Clinic at Cornell University, College of Veterinary Medicine. Please measure your cat carefully along spine , from collar to base of tail . We accept returns only for a shown defective garment and cannot accept a laundered garment for refund . This is a patented product . Joybies ! Home of the World Famous Piddle Pants(TM) !
