Bless you for caring enough to try to help this poor kitty. And you did the right thing by sending the money directly to the vet's on her behalf. Wow, three litters already! This not only increases the cat population, it's compromising mommy cat's health!
Somehow I strongly doubt that you'll hear from her but I hope I'm wrong for the sake of this cat and her babies.
I also find it hard to believe that you were criticized on the forum for offering some help and advice. Somehow I don't see that ever happening here at PT. You stood up and spoke for the cats, something they simply cannot do for themselves. For that you have my full support and heartfelt gratitude!!!
