Our neighbor moved out and left her pregnant cat behind, she had her kittens under our porch she's very young one now I have two baby's and momma cat in my bathroom the kittens need medical attention that I can't not afford I don't know what to do

Is there a discount for fixing stray community cats?

Lee's answer is based on the idea that Best Friends leave wild/ferrell cats loose. If your cats are not wild Best Friends may try to adopt them out.

Go to https://bestfriends.org/our-work/regional-programs/best-friends-atlanta to find out what you can do then Contact Best Friends via email. You will have to catch or trap the cats and take them to Best Friends but if you do they will vet them, spay and neuter them and you can put them back to live out their lives without breeding.
