my sons hamster went missing about 2 month ago!
anyway we never found it and at the beginning of this week,i started noticing a smell near my front door!
now it is really bad and it smells like a piece of month old fish

could this be a dead hamster or would you say i have another problem? if it could be a dead hamster what do you think i should do, i think i have found where it smells the most and i think it is coming from in the cavity of the wall next to my front door! any help would be greatly apreciated! thanks
