"Interested" You mean not trying to eat each other, right?

Because I'm only using Icky to breed to Sable and Tortuga, should I switch him 3 days with Sable, 3 days with Tortuga, back to Sable, back to Tortuga, or should I breed him to one until shes gravid, then switch to the other? I'm not in any hurry to breed, and I'm keeping my excitement on the back burner to the safety of my pets. I'm just on a quest for knowledge

I'm not planning on back-breeding, but I'll keep it in mind if need be. I've kinda assumed there wasn't much error for in/line/back breeding. Less hips to get dysplasia!

Also - I've got pictures up of everybody but Sable (I'm a bad mommy!) HERE. If you want to take a look
