We adopted a grown hamster last year & he's the best pet we've ever had. So lovely to handle & waits at the bars to come out. Recently though he's changed from sleeping in his plastic house to making a nest with the bedding in the sawdust in the cage. Somehow he manages to split the house open & remove all the bedding.
If it was high summer I'd think he was getting too hot. Is there a reason why he's doing this? DH thinks it's because he's getting near the end
