Thank you everyone for your help with Tommy. Unfortunately, Tommy passed away (we had to put him to sleep) last week. he had deteriorated to nothing and was not moving anymore. We thought the feeding, iron, sub-q's would help, but they did not. his CRF values were fine. We believe he may have had cancer and we did not know, since his vet visits focused on the crf and any physical exams did not find any tumors. It may have been deep in an organ, who knows. Tommy is in a better place and hopefully he will want to come back to us.
Thanks for all your help.
