I got my hedgehog Quillbert from Sunshine Quills. She is a wonderful breeder (at least in my experience with her) and I never had a problem with her. She made sure that I had been educating myself on hedgehog care and that I would have an adequate wheel and cage. If I remember correctly she also has a health guarantee on her babies so go ahead and take her to the vet. She may just be small. If that's the case then she should probably stay with the breeder for a little while longer until she gets to a more appropriate weight.
