What a gorgeous orange mama cat and her babies are adorable too. If two of them are torties then they're females. As you already know most orange cats are males.

I had an orange female cat when I was growing up and her mother was also orange and her grandmother was a calico cat. My orange cat named Puff had 2 litters of kittens and they were all orange because the father was also orange. She had 6 in one litter and 5 in the next litter and there were both males and females. I never even knew that female orange cats were rare until I learned about it here. It would be nice if the orange kitten was a female although orange males are very loving goofy cats too.
