What a gorgeous kitty family! I'd love to see the all beige one named "Chickpea"! One easy way to sex kittens is look under the tail (duh) and if there's two openings close to each other that look like a dot-dash under it's a girl. Males have a longer distance between openings, and it's more dot-dot with them. I think being five weeks they'd be easy to tell by now. I have trouble with longhairs sometimes. Then ya really have to dig around down there!
