Thank you everyone for your advice. Sounds like all our hammies have their own funny little ways
Tali is currently living in the Savic Plaza and has a 12 inch wheel. The wheel is right next to where she sleeps, her sleeping nesting spot is a very large bendy wooden bridge. The wheel she uses is enclosed, the idea of having one not enclosed is probably the best solution. I don't think there would be space for two 12 inch wheels as not much space then for her toys.
It is so loud when she runs on the wheel with food, she is upstairs in the spare room and can be heard downstairs (when the TV is off). I'm surprised it doesn't make her deaf!
I will give it a go with moving her hoard to another corner near her (just not the wheel), but probably the best solution is trying a different wheel in her cage. Tali is about 1 year 4 months old now, so not young as such however she is tons of energy!
