Wow those are some impressive weight gains Gus, and nice to hear they are enjoying their new diets.
We tend to limit wheel time only for growing pups who seem to have a real obsession with wheels, we have had some who literally run themselves to exhaustion. And they get extra out time and extra play things to compensate. You do find that as they mature they are less likely to overdo the wheel, and in fact some of mine very rarely use a wheel at all.
Just as an aside, our Vala used to have a silent spinner which she never used at all. Last night Arti decided to swap this for Bronte's wodent wheel, currently removed from Bronte because of her having the litter.
Vala went in it and spent about 5 minutes at a leisurely jog, before coming out and spending 15 mins munching on carrot and swede cubes with popcorn to finish! (plain popped corn without sugar/salt of course). I guess that we can safely say she isnt a wheel addict!
She's the hamster equivalent of people who spend 15 mins at the gym before then buying fish and chips on the way home!
