We recently took in a litter of four stray kittens. Long story short, their stray mama got killed, we discovered their existence four days later, and we spent about a week getting them all caught.
We caught one, and then another the same day. For the moment (and for my Facebook page, which suddenly was the most popular it had ever been because TINY KITTENS), we called them “Thing One” and “Thing Two,” and then “Blackie” and “Brownie” (which were never intended to be permanent names).
That night there was a big storm, and Three and Four didn’t show up till the next evening, but we caught them together. Since One was black and white and Two was calico, we decided to continue the pattern and designate the second black-and-white one “Three” and the second calico “Four.”
OK, so now we needed to get them to the vet, where they’d need “real” names. At this point we were figuring we’d keep the first two and find homes for the other two. So we basically needed “throwaway” names.
Mr. S came up with the neat idea of naming them with names that were kind of like their numbers. Reminiscent. Suggestive of numbers. OK, so we came up with:
Ace
Doozy
Tribble
Quark
As it turned out, Ace and Tribble are boys, and Doozy and Quark are girls. And as it also turned out, nobody really came forward to snap up any of the extras in that first week, and in the meantime, you can’t take care of four ridiculously adorable kittens for a week without falling madly in love, so . . . we now have four cats. 
They were about 6 weeks when we caught them, and now they’re about 5 months old. Tribble already weighs 8 pounds! The boys have been neutered and the girls go in next week. And yes, we are crazy. But they are so much fun!
