I don't know where to start. my kittens are male and are 10 months old. Dennis had disappeared 4 days ago for 2 days and as soon as he came back he was in a poor state where he didn't want to eat at all because he was in pain... so we took him to the vet and he told us he had a fever of 40 and we left him at his vet to be administered term. Today, unfortunately, his brother is facing the same symptoms, where he has diarrhea and is not eating at all because he is in pain.. The vet told us that it might be FIPV.. Unfortunately, I do not have the financial ability to help them. Please help me to save them
