My cat is 20 years old, and besides having diarehha most of the time, he has a usual appetite and is still mobile. His meow has gotten louder and we thought that he would pass on by now and was wondering if we should put him to sleep? We don't have the money to spend for vet costs and seem that since he's been living for so long, we would hate to take him to a vet after all these years and have them tell us "He's old". We took him when he was young and got his vaccinations, but must have done something right since he's lived for so long. We also have an 18 year old cat that is still as lovable as ever. What should we do? Wait, or put him out of his misery?
