Help End Aries’ Suffering

My seven year old cat started throwing up Friday afternoon and hasn’t stopped since, he’s progressively gotten worse, lethargic, and he’s in pain. He has since started pooping blood. The vet’s office  is closed, but opens Monday morning and I’m going first thing. I don’t want my baby to suffer, but I literally have no money and live paycheck to paycheck but I can pay back whatever anyone loans me if you can’t donate, I’m desperate guys. Please, I don’t want him to hurt anymore.
