wow. last winter my sil was using these for her dog, and we both thought they would be good for Emma. so I took a couple of pads home and put one out. Emma of course clawed at it, chewed a teeny bit. and in the next ten minutes she started acting really out of it. thankfully she only got a little bit of the attractant and was able to come out of it herself, no vet visit required. but still, it was scary when it happened.
