Call animal control, they will set things right. Just make sure when you buypermethrin, if it is a concentrate, read the directions on it so you can dilute it, otherwise, it will give them chemical burn. I learned that the hard way. And absolutely do not bath them until they are healthy again, or else they can no regulate there body temps, and it will give them hypothermia, and you will have to dry them off with a hair dryer, and put them in a warm room until they are warm again. I learned that the hard way too. Good job saving them!
