input: [1] Degu is not walking correctly, may avoid using certain areas of foot. Limping, getting caught on fabric/carpets, or possibly accidentally scratching other degus. [2] Nail growth [3] Lack of rough surfaces to wear nails down. Rear nails often grow more rapidly and wild degus encourage nail wear through digging.

Long nails can be worn down by placing a small square of fine sandpaper in the running wheel for a few days- remove after this to avoid sore feet. [5] GOOD [0]
