If you can't take him to the vet, you need to find a new home for him that is able to. You can contact the Hedgehog Welfare Society and they can see if there's a rescue station anywhere near you or if they have any prospective adopters in your area that would be willing to take him. Hedgehogs require vet visits and can often be quite expensive. You should not keep him if your mom isn't going to be prepared to help pay for that cost - it can easily reach & pass $500.
