Amputation costs for my kitty

Anyone who knows me, knows my love for cats. I got a call from the Calgary Humane Society, saying they found my cat. (They used her tattoo to locate me) My cat Lexi was my sons cat, that vanished two years ago. Boy I was shocked and excited to hear this news! However She’s in pretty bad shape as someone in this city shot her in the front leg and shattered it. The Humane Society did a wonderful job stabilizing her to transport to the vet. I picked her up and rushed her to the vet. Its cost me $3,000 so far as she is having her leg amputated. I had two choices here, and putting her down was not an option. She’s family and I have to do everything in my power to bring home my long lost soon to be three legged kitty. Please help support.
