If you blow on Muffin’s fur, do you see rings of alternating light and dark? That’s the hallmark of the chinchilla color. 🙂 I was thinking that’s what he looks like as well. I think the chinchilla color can be on other breeds as well.
Pinky could be a NZ mix, or also could have Rhinelander in him. Sometimes I think the Rhinelander breed gets thrown around too much, since the broken color pattern can pop up in lots of breeds, but seeing him with the litter and all of them having nearly identical markings makes me think maybe he really does have something like that in him.
I’m not sure if I have mentioned this before, but Pinky’s markings may also be related to his poop issues. I didn’t want to bring it up right away, but seeing his siblings all with the same pattern makes me think I should (and knowing this is an ongoing problem even after ruling out some things with the vet). That patterning is linked to genes that are linked to megacolon/cowpile syndrome. I’m mentioning it because preventative management can help it keep it manageable and there are some dietary things that seem to help buns with this condition. It details it here: https://vgr1.com/megacolon/
Even in buns with these markings, the condition is rare, but given that Pinky’s been having weird poop issues for a while it might be worth thinking about.
