I have a rat who is about 5-6 months old (we found him in the driveway as a baby just before New Years and decided to keep him). He is very placid and friendly, only I noticed last night that he has all of a sudden lost HEAPS of weight, and now I don't know what to do. He is still grooming himself, etc, but I know that weight loss in rats is usually a very bad sign regardless of whether they are still eating and grooming themselves, and that they can die within 24 hours. I plan to take him to the vet this afternoon, only the local clinic says that they do not specialise in rats and I may need to see a specialist, who is very far away, not to mention expensive! Anyone have any ideas what could be wrong with my rat and what to do to keep him alive if I can't get to a vet for a couple of days...
