I know it all too well Rose! Most of the kitties I rescue off the streets are cared for by me at first until I finagle them into shelters! I just got in an emaciated orange boy via leslie flenner who is a hard call. I'm sure he'll survive for now, but I don't know what's wrong. Sweet neutered orange boy...age who knows? I've had kittens with awful teeth, so how can a vet actually tell by teeth? I can tell if they're over six months, but born to a feral who's been reproducing for years, it's anyones guess IMO! Jan
