I ended up taking Popsie to the E vet to get an enema. Last week at the vet he weighed 7.2, now he weighs 6.2
The E vet looked at a copy of his blood work and didn't seem to agree that Popsie has CRF. She wanted to do a urinanalysis but it would have been too expensive. He's having another panel done on May 20 to check his ALT and Ca levels again. I will tell them to check his urine that way I'll know for sure if he's got CRF. He's just been going downhill in the past three weeks. I hope this isn't the begining of the end.
