We had kept 2 of our girls intact in hopes of breeding with our Munchkin, and today one of the girls had her babies. It appears that perhaps she got together with the foster Russian Blue that we had in the cat room for a while instead, since all 4 kittens are blue ^^; Still adorable, but we could have asked more for Munchkin x Siberian babies than we'll be able to get for Russian Blue x Siberian babies... It's still possible the Munchkin is the daddy, since momma has blue coloring as well and only half of Munchkin babies are born with short legs, but since the Munchkin is silver tabby and white, it's unlikely.
