When i took Kiara into the vets, i asked for some help for nail clipping! She said that i could put a piece of sand paper on her wheel that will file her nails down when she runs on it! Is this a good idea? I was scared that maybe her feet will get really raw or start bleeding if she runs to much! My hedgie is very shy and huffs everytime i come close, so i dont know how well nail clipping would go! I dont want to hurt her! Help please!
