Hi, so my piggie Finn is about 5 years old, recently he’s just stopped eating and seeming slow and tired, the vet thought it was his teeth so i gave him painkillers to see if he would eat but he still wasnt really eating, only a few veggies. I took him back today and hes there right now getting a scan, the vet suspects it could be renal failure, hes lost weight, tired and again no appetite. He hasnt been peeing excessively or drinking a lot, but theres no way to tell whats wrong without blood work and a scan so I'm doing the scan first. Does it sound like kidney failure? The vet mentioned sometimes they smell very strong of ammonia if they have kidney failure but he doesnt..? Any help or advice is appreciated, i dont want to give up on him
