1. get a big cage or atleast a safe area you can take him out to at night for
an hour or so.
2. get a glider safe wheel, I think this is very important, will give him
something to run on while in the cage. he may not use it at first but maybe
over time. get custom cruiser or raptor (www.mygliderwheelsandmore.com/shop-for-wheels.html)
or my favorite
atticworx.com stealth or freedom wheel. this webpage is acting funny but i did
get it to work.
3. get him on a healthy diet, consider getting him a friend, and maybe start
adding some stuff to his cage slowly. toys, foraging cups with treats.
mealworms they love.
4. I would also recommend keep calling the vets in area and see if one will
see him anyway. specially if you can afford it.
