I'm so sorry to hear about this. We've all been there and know how difficult it is to let go. Try telling yourself that it isn't about you right now, it's about Fluffy and his quality of life. And most importantly, you don't want him to suffer. He's been good to you and vice versa. And if you have to do this last act of kindness for him, then you'll be strong enough to do it because we here at PT will be sending you the strength you need. Hang on to your strength but, if the time is here, let go of Fluffy. He won't hold it against you and he'll be so much better off. Hugs to you and Fluffy.
