Beautiful, beeeaauuutiful rats!
I'm just getting involved with manx (I only have one male Manx), so I can't say this based off of experience....but I've always heard that female Manx are either sterile or that if they do get pregnant, they have difficulties giving birth. Have you ever witnessed this?
Please, keep this thread updated! I'm very interested in this! I'm trying to learn as much as I can about the Manx.
