Dear friend,
Your hamster has a bladder or kidney infection. Antibiotics are the proper way to treat it, however, it can take several days before you see improvement.
In the meantime: You must keep the little guy VERY warm. If he is cold he is not going to get well. Also make sure he ha a LOT of water as that is essential.
Make sure you clean the cage very well too or aspergillis fungus can develope in the spot your hamster urinates.
This condiions sometimes comes from a high fat diet as that causes his urine to become more alkaline.
If he is not better in a few days you willl need to take him back to the vet.
Please let me know if you have any more questions or need any additional help with your dear little hamster.
Warmest wishes,
Terri
