I euthanize my own rats. I gas em and freeze em to MY standards. Kept clean and what not.

You know what?? At a local show we just had rodent pro was there and I had a chance to go through they're supply. After seeing them ill never buy from them. Sure they have good prices. But all they're rats were just yellow. It was gross.

I'm asusming that's because of the urine. It just doesn't look sanitary. Just my experience.
