Yet again I found something which I originally purchased for the Chinchillas that would've been a complete waste of money if I didn't have other small furries to road test it too.
Left it in the Chinchilla cage for over three weeks and during that time all they did was sit in it every now and then with a kind of "well what's it supposed to do?" look on their faces. It was when they started chewing it that I decided that they probably weren't going to use it for its intended purpose so after a good wash I offered it to the three Degus who had just about destroyed their wheel and were looking rather disappointed that they could no longer go round without falling through the hole they had made.
This wheel not only needs a flat surface, it also needs a fair bit of clearance around it too so I needed to have a major shift around in the cage to fit it in but was worth it. It took the Degus about ten minutes to get on it, curiousity gets the better of them every time, then about a further ten minutes to work out how to run on it. Took slightly longer to work out how more than one could use it at a time without flying off but only by a matter of hours.
If I had any complaint it would be that there is no way to fix it down so every now and then it moved towards the edges of the cage and didn't turn as freely as it should, initially the noise of it grating against the bars put them off a little, now it just annoys us rather then them.
Would recommend for smaller animals, our Chinchillas just weren't interested, but then maybe that's just ours.
