Hope the kitten gets to the vet's right away for a checkup and its shots?
Many ferals have assorted diseases that need immediate treatment, but if your daughter has cats, she probably already knows that?
We've had a few feral cats around our camp over the years and the only reason they didn't get thumped, was because we have tons of field mice, voles and deer mice around there.
Some years ago a neighboring farmer had a stray cat show up at his place and "blend in" with the barn cats. Within a week or so, it attacked and bit him on the thigh. Cat was shot and tested, rabid. So he had to go thru the shots and all his farm cats were killed and buried.
I am not a big fan of feral cats, especially out in the "middle of nowhere". Not only can they transmit diseases like rabies and distemper, they are hard on bunnies and ground-nesting birds.
Idiots from town usually take unwanted cats/kittens out in the sticks and drop 'em off to fend for themselves. But for some reason, it is apparently unacceptable to shoot them, as well as their cats?
Buddy of mine once caught a guy dumping a box of kittens on his farm, in a little gulley along the road. He went down there with a flashlight, wrote the guy's plate number down and told him he was calling PSP. Took the guy almost an hour to round up the kittens in the briars and thick brush, while my bud stood up on the bank shining his Maglite on 'em.
My guess? The dimwit probably drove outta sight and dumped 'em out again, down the road.
