About a year ago we had a cat who took up residence in our back yard but we couldn't catch her. Evidently she was covered in fleas and so was our yard and we had to call Terminix to come take care of it. Our guy told us to walk around in white socks and you would see them jump and sure enough they were hopping! He had to bomb and that took care of them. This was after Mercedes went to RB and before we got Gracie..so we knew it had to be that cat. (Don't know what ever happened to the kitty, she hung around a couple of weeks and then was gone..even tho I did put out food for her..maybe she found her way home, rather think that then her getting run over!)
