I so totally understand! I hate it when people think that they can just use them, abuse them, and then throw them out when they're done. That, I suspect, is how I met Clover, and her owners just threw her out when she stopped looking so kittenish. And then my friend and Clover's foster mommie, Mel, had a friend (not so much anymore) who believed that it was '"dirty" for cats to come inside, and if the cat died, oh well, they're all lesser creatures than us humans, and were just created to serve us in any way that we please" sort of thing. So horrible!
I'm glad you did what you could for those babies!
I'd do the same thing!
