My mom and I found a stray cat this weekend. Actually, it found us... just came right up onto my mom's porch. It looks really bad... It was so skinny so we gave it some kitty kibble which it gobbled up. But soon after it threw it all back up. So, we gave it more food and it ate it and threw it up again. I guess this explains why she's so skinny.... It's also got several hard bumps on its back. The largest one is greyish in color and looks crusty and pretty disgusting. It's got to be sick with one or more problems or infections. My mom and I feel terrible for it, but my neither one of us can afford another pet, espcially one that's sick and in need of a lot of medical treatment. Can anyone in the Pittsburgh, PA area help this kitty out? We've called around to the no-kill animal shelters we know in the area, but they all say they can't take another cat because they have too many already. We don't know what else to do Please help!
