Medical cost, Support Miau’s surgery

Hi! My name is Ali i have a cat his name is miau, he recently went outside to play as always, but someday someone broke his leg, I don't understand who and why but now he needs a surgery for $4000 if not he will never be able to walk. The operation consist in cut a little piece of his broken bone and then add a nail. I put the the deadline for this crowdfunding in a week because if we wait for more time his little bone may start generate necrosis and I don't want him to lose his leg. Or if anybody knows a doctor who may help for not so much money here in Mexico Guadalajara I will appreciate!
