Pet Questions? Ask a Vet and Get Answers ASAP
Did he eat/drink normally today?
What temperature do you think his cage/room where his cage is is at right now?
If you have a heating pad I would put it under one end of the cage, so that if he wants more heat he can move to one side of the cage. A heat lamp may heat the whole cage and it is harder for him to move away from the heat. He probably will not dehydrate in the next 12hrs before he is seen by your vet but I would keep offering him water with the dropper until you go to your veterinarian tomorrow.
Also if you have a humidifier you could set it up in the room where he is. It could help his breathing. With these little guys any added stress should be avoided. No extra handling, keep it dark in his room. Make sure he has access to his food and water. Get him to your veterinarian first thing tomorrow.
If you have any other questions please let me know.
I don't even know if that remedy has even been tried in a hamster. So to be on the safe side I wouldn't use it. I don't believe there are any published guidelines for dosage.
