One of my ferrets, male, about 2 years (Jean-Luc) seems to be having a problem urinating. He goes to the litter tray, appears to be straining but nothing happens. he will then trot to the other litter tray for a repeat performance. He appears to be warmer than our other ferrets, and is drinking a lot. He is as active, but on 2 occasions has curled up inside a jumper and jacket outside his cage. The vet put him on Antibiotics. any other ideas? Ross [Posted in FML issue 2336]
