If a dog is suffering from cancer, and it’s getting worse is it best to put them to sleep? My mother doesn’t, but Funny duck I am silly but I am free shirt feel like I should put my feelings aside and have her be put at rest before she suffers more. My demon cat Napster made it quite clear when it was time to go. He had been in decline, and the vet told me that it was a matter of time, but he was still himself in the various ways that mattered. There came the day when it was clear that he was dramatically different and his discomfort and helplessness were obvious. I made an immediate appointment to take him in, had a final conversation with him along the way to make sure he was hearing my voice and knowing I was present, and held him to the end.
