Yes, I think we all have had at least one pet we weren't sure if it was time. One I should have done sooner, now that I think of it. So, once the decision is made, remember everything has its time. "To everything there is a season."............ . It just that in a sense, it bothers us because, WE made the determination, not nature. In a perfect world, we all hope that everything just sleeps away, and no one has to make that decision for them. I have an old cat, and just put my 15 1/2 year old dog down in Dec. My companion.
