This lady's probably some sort of collector who can't handle all the kittens. I'm glad you took them in and I don't hold it against you that you can't keep them, at least you are giving them a chance. I don't remember people dropping of animals at the farm I lived on as a kid but I'm sure thats how we got a few cats. Lakeland is out in the middle of nowhere and we get dump-offs. People seem to think that students will take home their cats(which they do if they can catch them). We have a black one thats a little over a year old and showed up last October out of nowhere. The cat colony at Lakeland has only 4 adult ferals right now because most were taken in by students, they are all grey, how did we come across a black cat that isn't accepted by the other cats? I'm sure she was dumped. I hope you can recognize her car or her if you should see her somewhere and tip off the police on this lady who is dumping cats. Good luck with the kittens I hope they all make it.
