MizMelly -- your Jack does look like he knows something the rest of us aren't privy to! You're a sweetie to save the two of them.
I checked online about the orange kitties being mostly male. It's true -- 80%/20% male to female ratio. Apparently, the orange color is in the x-chromosome, & the orange in both x-chromosomes in the female fights until one is left standing, & that's where calicoes come in (they're almost always female; males are rare). If someone has a male orange cat, he has an extra chromosome (xxy), because the orange color is only in the x-chromosomes but he's male. And sterile. That's about as much as I understand about it, but I thought it was interesting. Especially since I hadn't heard that orange cats are usually male until several months ago.
