It is real hard to put an animal down, we had to today for my 19yr old cat, Hilde. All of her organs were failing, just overnight. It is the humane thing to do, no matter how hard it is. She pulled through for so long and was determined, we wondered how long she would make it. We could not see her suffer anymore. Im glad we go to good vets, after all your animals become part of your family and life. I also am glad to been able to have that many years to be blessed with a one of a kind animal.
