My cats intestine surgery

A couple days ago my mom, aunt and myself noticed that Pancho was looking down. He stopped eating, drinking and even moving. The last time he ate something was Monday night (Oct/05/2020), but unfortunately ended up vomiting every single thing. After that I told my mom that we should take Pancho to the vet or an animal hospital so they can take blood test or X-ray to see what’s wrong with him. We then took him to a animal hospital this morning (Oct/07/2020) to get some info on what is happening with him. The doctor said that he has Gastroenteritis. This is an inflammation of the gastrointestinal tract, meaning the his stomach and intestines are swollen in some way. The surgery is around 3000 to 3500, and I do not have the money for it. So I please ask for your help!! I don’t want to lose my precious baby, he’s only 1 year and a couple months old. I would really appreciate if you could at least donate $1 dollar. One dollar per person might be enough to save my cats life.
