Rats become sexually mature at the age of about five weeks, which means separating bucks from females and neutering them immediately is essential to prevent unwanted litters.

- Firm and well-rounded body
- Clean nose, eyes, ears, and rear end
- Clean and well-groomed coat
- Healthy skin on the ears and tail
