I've always thought that the tabby kitten was female. If, once I get a good look, it turns out to be male, I'll be 0 for 3. But I think I have probably been right about the tabby. The two kittens who vanished from the original litter of five were probably the males, and it was probably Tommy Two-Tone who snatched them. He probably killed his potential rivals and let the females survive as potential future mates.
The kittens have probably outlived Tommy, though. I haven't seen him since a few days after they were born. In fact the night he probably snatched the last of the male kittens was the last time I remember seeing him. Old Gray cat, small gray cat, and Alger all disappeared about the same time. I thought it was only Farah running them off that kept them away, but now I'm beginning to think that animal control might have made a visit to the ares and trapped a lot of feral cats about that time. If they did, then Farah was saved by being stuck here with her new kittens.
But four female kitties could prove to be a real problem in the future. Especially if they all think of my yard as their home. I could end up feeding an entire colony of cats if they all get pregnant. Oh, dear. Time to see about some spaying.
