Hi, akane- no, not the babies- you have 2 does (?) that look similar. In the last photo one is in the greyish litter pan or crate bottom, and the other is to her left lying to the right of the black bin. They appear to have the nose marking of a Ca., but I can't get a good look at the rest of the bunny... they almost look like they ran through ashes or something, and they just look like a really cool color to me. Any chance of better pics of those 2, and what are they?
Your babies are adorable also- I'd gladly take your curly kits!
