We do have a little French bulldog-so while all attempts are taken to ensure no errant hairs have made their way onto this item-it is a possibility-so if you or someone in your home are highly allergic this may not be a good source for you. He also attends doggie daycare on a pretty regular basis-so while we do not own a cat there is a very remote possibility that another dog may transfer a cat hair to our dog. WE DO NOT OWN A CAT!
