Well I have a big tabby cat, and we got him as a stray so we don't know how old he is, we're guessing he's 15 years old, we got him 6 years ago. Well the past few months, he's been losing his fur color, having bad diahrea and just yesterday half of his face was swollen and today it's blood. He's having trouble breathing and he keeps getting worst everyday. What should I do? I think we should take him to the vet, but my parent's don't have much money or time right now, I'd pay for it, but I'd need to get there. My mom won't take him to the vet, I think we should put him to sleep. I can't stand seeing him suffer like this.
