Care for Rescued Mama Cat and Kittens

Hi! On April 3rd, I found a mama cat and a box with her 4 kittens dumped by my home in Staten Island, NY. I don't know why someone would dump them, nor do I judge it. I am asking for help to get them vetted and to help with food and litter. I don't want to ask any local rescues for help due to kitten season already being in full swing, and many are trying to help with the survivors of Happy Cat Sanctuary. I understand money is tight for everyone, including me. Even a dollar would help and I would be extremely grateful. I just want these babies to have enough food, litter, and vet visits for shots, deworming, and getting fixed before finding them homes.

Even if you can share, that would help.

Thank you for your time.
