Sleeping under their wheels suddenly?!

[HamsterLady]

Hiya, I went in this morning and noticed one of my dwarf hamsters was sleeping buried under it's wheel. Went in just now and the hamster next door is also doing this! He's burrowing away under his wheel next door (separate cages).

The only change in there is the addition of a fish tank last night, and the filter does vibrate and hum. However it was switched off in the night, and the first hamster was already doing it before I put the filter back on this morning.

Only other thing is that the central heating might have made the room warmer than usual? I'm not worried exactly, more curious!

It is likely the heating being on making them feel warm and so adjusting the nest to a more cool and open position.

My hamsters do it althe time

JJ has about 5 spots she likes and will change it up ever once in a while but with all the changes in temperature over the past 2 weeks and heat going on and off she keeps changing her sleeping spot every 2-3 days. Every morning its a new game of "wheres JJ"?!!
