Wheel advice please, pics

This is shadows wheel ( he won't be having it in his viv till 12 weeks old) I bought it from a hedgehog facebook page ( don't want to name ) can you tell me if this is OK, I am just a bit concerned about the back of the bolt sticking out at the back and if he goes round the back of the wheel and jumps up to sniff and he gets his feet inbetween the upright and the back of the wheel, inside the wheel there is a metal washer to with little gaps all the way round don't want him to get toes or claws caught...... sorry if they are sill y questions but being first hog don't want him to get hurt....

i know what wheel it is....im sure it will be ok...its a similar built to larry's wheel...

Most of the bucket wheels are made like this - he shouldn't come to any harm - haven't used this wheel I tend to stick to Larry's wheels - see how you go x

Thanks Tayer and Helen, I might think about getting one of Larry's wheels but they are not ordered very often are they? I think I have just missed an order...

Tayer has started another order I think x

will go check it out............

Will see if I can bump it up for you

yeah i started one...march order.
