Fangs Surgery

Anyone who knows me, knows I regularly do as much as I can to help animals in need. I donate to charities and I raise funds through my art. Unfortunately this time I am trying to raise money for someone much closer to my heart, Fang. The last week he has been extremely unwell, showing symptoms of a tummy bug, only to realise when we took him to the vet yesterday morning it was something far more serious. He had an X-ray which showed his has swallowed something (part of a toy we can only assume at this stage) that has lodged into his intestines making him extremely ill. Yesterday I paid $550 to have him scanned, treated for pain and nausea, as well as a drip to keep his fluids up, as well as some medication hoping to push the object out. Unfortunately none of this treatment worked and this morning we were told we have two options. Taking him to emergency where he will have surgery to remove the object and to assess the damage done, or to put him to sleep. This was not an option. We went through all the risks of the surgery and understand that we cannot predict what the outcome we be, however we can only hope that everything will run smoothly. Unfortunately the surgery is $4000 on top of the money I already paid yesterday. This will cover the operation, pain relief, a drip, and overnight care to make sure he recovers smoothly. After emptying out my bank account and with the help of my mother and grandmother, we were able to lay down the $2000 deposit today. However there is still a remaining $2000 in which I need to find within 24 hours. I understand that this is an unrealistic goal, which is why I currently have it set at $900, because every cent I can get will help me greatly. I also understand that as an owner, I am responsible for looking after him, so it really upsets me to have to rely on the help and good hearts of others. If you can even donate a single dollar, I will be eternally grateful, and i'm sure Fang will be too.
I will do everything I can to make this work, and if you could just help me get closer to this goal, it will give me some time to figure out what I will do for the rest. 
Thank you so much for taking the time to read this.
