My Dumbo rat Dole is sick. He has been for a few weeks now but I thought he was getting better. He is now the worst I've ever seen him. He is older. About 1 and a half to 2 years old. He is breathing so heavily his head bobs and his sides cave in and out. He is clicking and slightly weazing. He is barely moving, doesn't want to be taken out of his cage, and doesn't seem to want to interact at all. He actually started chewing on the bars of the cage today and just stopped. Basically supporting his head by having his teeth around the bar but not chewing. He sat like that for about 5 minutes before I moved him. I have seen very slight leaning. Not even really enough for me to be sure about Including it. I know this is all over the place but please tell me how I can help (besides a vet. Unfortunatley we do not have an small vets where I'm living), what could be wrong, or how, if its too bad, make his passing any better? I'm really hurt I can't help him.
