Chevys surgery

Last night me and Chevy got into a little accident with the stairs where I was in a rush out the door and I then realized I forgot my phone inside the house and I rushed back down the stairs in the dark and chevy was at the bottom and didnt move in time when I was rushing down the stairs in the result I ended up stepping on him and he couldnt walk on his leg and was crying non stop .....i rushed him to an animal hospital and got the worse news that his leg was broken and needed surgery now he is still at the hospital and went thru surgery just dont have the funds to pay for it and they won't expect payments .......I'm just asking for a little help so I can pay the vet and bring him back home
