Here is what a School of Veterinary Medicine representative has said : "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, my cats seemed to become accustomed to the pants relatively quickly." "These well made overalls can be machine washed and line dried".
