8" wheel

[kim]

I want to upgrade my gerbils wheel as they currently have a 6 inch wheel which they have grown out of but am struggling to find them most seem to be either 6" or 9" and I don't think a 9" will fit in there tank so would prefrably like an 8". The only one I've seen is this one www.amazon.co.uk/Superpet-International-SSR61394-Around-Wheel/dp/B0002AS94W/ref=sr_1_67?ie=UTF8&qid=1424861854&sr=8-67&keywords=gerbil+wheel#productDetails which is a kaytee run-around wheel, dose anyone know anywhere else I might be able to get one for a better price in the UK (I'd preferably want a mesh wheel with opening on both sides as well)

Thanks

These are two wheels I found on viovet which are reasonably priced, one is mesh the other plastic but both are only open on one side. both are around 8 inches though they go by centimetres so I had to wap out the converter

I would personally go plastic but it is completely up to you.

I use these ones for mine and they are fantastic
