Help Tigger Recover from Emergency Vet Visit

This is Tigger and he needed a Hail Mary. About 8 months ago I saw a Facebook post about a woman in desperate need of her 9 cats getting spayed and neutered as she was burying too many sick and unborn kittens. She was u able to contribute financially. Myself and my friend/colleague responded to her post and personally funded and transported all 9 cats to get fixed. Fast forward to last night the owner messaged me on Facebook asking for my help. Tigger had witnessed his brother passing away now was asking lethargic, drooling, bleeding gums and not eating or drinking. Being a an animal lover I couldn’t tell her no and just let poor Tigger die…. So I took him to the emergency vet. Im already financially tight but again, my conscience would let me allow a cat to suffer. Any donations would be welcome.
