Help save Mamas' leg: cat hit by car needs surgery

My name is Adam, and I have a soft spot for strays. Mamas is a stray cat who sauntered up to me one day and -- because she got fed -- has never left. She lives outside, but she's become my responsibility.

She went missing for a few days recently. I looked all over but I couldn't find her. She finally came home, but it was obvious she was hurt. We went to the vet and one of her hind legs is shattered, likely because she was hit by a car. Now I'm trying to save her leg.

Mamas is the sweetest, most annoying girl. It doesn't matter how you touch her, she's going to purr up a storm. She's a fiend for food, and I think she's had a rough life that made her desperate to eat whenever she can. As much pain as she's in, if you didn't notice her leg you wouldn't have any idea. She's just a baby.

Mamas needs surgery. It's going to cost about $5,500 to save her leg, and that's what I want for her. She deserves real love.

Anything you can do to help save Mamas' leg will be appreciated.
