Oh my goodness!! They are adorable. I am so glad the momma is doing well with you.
As for names, I'm not very good at it, but for some reason when I looked at male #1 the name Rocky just popped in my head. I think it's because his little face is all squished up and it looks like he was in a fight and his face is swollen. I'll see if I can come up with any other names for the other nameless guys.
