Bunny, I'm so sorry to hear this sad news about Fluffy. Like others have already said, he will let you know when its time. My Pepper let me know that he had enough and I wasn't about to sit back and watch him suffer any more so I had to have him put to sleep. I know it's a very hard thing to do but it's even harder to watch an animal suffer. You and your family will continue to remain in my thoughts and prayers during this difficult time. Please take care. (((HUGS)))
