Help Aki's Surgery

Aki is 11 years old and a very sweet girl who loves to cuddle and sit on my lap, a very clingy one. She'll always jump to the couch and sit with me until Monday night when she started to stare at me and didn't eat which I ignored since it's already late at night. She started having diarrhea and won't drink or eat. The following day, I made a soft food for her which she always love to eat but never ate it. In order to drink, I would get a spoon and put it close to her mouth so she can drink. On Wednesday, I boiled some chicken to try to feed her and luckily she ate that, so i did that Thursday as well. Friday morning when I woke up, Aki tried to stand up but fell right off on her side and I teared up and decided to get an appointment to see the vet as it's been 4 days since she's been feeling under the sun. The vet immediately advised due to pyometra (closed build up puss in uterus that might rapture and can be fatal) that we would either have to give her surgery or euthanize her as the surgery will be expensive. Aki kept looking at me and my partner as if she didn't want to be put to sleep just yet. Although we don't have a lot of money saved we decided to have the surgery since Aki is a fighter and have high spirits, with full of life. She'll be in the hospital tonight to get some IV to get her prepared for the surgery. We seek out your help to support Aki's surgery. Any amount would help a lot. Thank you so much in advance.
