Oh, my! How horrible! After Hurricane Hugo hit in NC, a stray kitten came up to our house. I took it in, fed it and almost had my husband convinced we were going to keep it. I went out in the garage a few days after it showed up, and saw a puddle of blood, then saw the kitten vomit up some more. Took it to the vet and it turned out it had feline leukemia. That was a pricey almost-ours kitty.
