Gini, I'm just now seeing this. I'm glad to hear that Rascal's dental went well and that he didn't have to have any teeth extracted. I sure hope that the growth under his tongue will be benign and that you'll get your birthday wish of a healthy cat. He was probably losing weight because his gums were hurting him and his sister wasn't letting him eat. Lots of prayers and positive thoughts are being sent his way. Please take care. (((HUGS)))
