It was a few years ago, I think there were 19. We took in some "Feral" cats who were on the wait list to get spayed-- they gave birth within a few days of each other. It happens, but it was the first time that we had 4 foster cats all birth at the same time. They were great moms and even fed eachothers kittens, come to think of it that pile started out as a nursing mom with some kittens.
Everything that happens, be it the good, the bad and the downright miserable define who we are.
