Hamster grumbling noise

just wondering if my hamster is ok
   
i only got him a month or 2 ago and recently its not sleeping in the house but in the corner of the cage and there is a slight grumbling noise from it like its hungry but it still has food in the bowl i know its eating and drinking and ive checked for like wet tail and watery eyes but everythings fine just the grumbling noise, been making that noise 2 days now
   
you think hes ok?
   
i cant find anything at all on the net about just that noise, everything else says like wet tail and mushy droppings but my hamster doesnt have any of that

Hi, i am not sure about that! I have never heard of that before however my friends hamster made grumbling noises but it was fine. I dont think you have anything to worry about, just make sure your hamster continues to eat and drink!!
