Sleepy hamster

Question
So my hamster has been sleeping for 2 full days now. He only gets up to eat and drink but yesterday he actually got up and collected some food in his stash and even was running in his wheel(for a bit but he was running). I also checked for other symptoms of sickness like runny nose, wet tail, matted fur, watery/glassy eyes and other symptoms. But what worries me the most is that he is not as active as he was before. Before he was all over the cage and play pan, climbing on the bars, trying to escape even chewing on them. Please answer as soon as possible. Thnx

Hi Eleonora

Thanks for your question.

Firstly, how old is he?  what type of hamster is this?

It is hard for know for sure what is happening and it might be a case of doing some detective work:

When he walks, is walking normally or dragging a leg, or not wanting to walk?
Is he eating normally?
Have you examined his poo?  Is it normal, or is it wet, soft, such as diarrhoea?
Has his water intake increased at all?
Is there any possibility he has fallen when playing?

Hamsters can develop illnesses that humans get - they can have heart problems etc, which cause them to slow down as they become breathless.  They can also fall and wind themselves.

One of my young Syrians, Marley, used to climb a lot - he was always hanging from the top of his cage.  One evening I found him in his nest ice cold, barely moving.  I thought he was paralysed as he couldn't walk, and was floppy.  I was convinced he was dying, that perhaps he has had a seizure or had fallen from the cage and hurt himself.  I sat with him all evening trying to keep him warm, and returned him to his cage expecting him to die.  However, the next morning he was back to his usual self and he is fine now.  I have absolutely no idea what happened and why he behaved liked this.  

Apart from looking from any obvious signs of illnesses - diarrhoea, constipation, breathing problems, walking problems, excessive drinking, any blood or discharge from his rear end, any change in body shape etc. and ensuring that the cage is clean, in a warm dry part of the house, not near any plants or air freshners it is difficult to identify what is wrong.  

If you are worried, and if he deteriorates in any way then I suggest getting a vet to check him out if possible in case he needs medication.
