Help Shuri live more than 3 years

Hi everyone I am fundraising for my cat Shuri. She was rushed to the emergency vet October 2nd. She has lost 1/3 of her body weight and refuses to eat or drink. In order to get the tests she needs we need to come up with the 1700 out right. The vet says if we don’t get these tests done she may only have a couple days to live. She is only 3 and has a loving sister who would be loss without her. She also has a 10 year old human sister who also would be devastated. Help me get the tests needed so my baby cat can live a happy life.
