They worm their way into our hearts

Not in a good place today. 
Our beautiful Oscar won't be with us much longer.  He apparently has a malignant tumor on his liver and spleen and maybe three months left to live. While speaking to the vet on the phone I was given the option not to let him wake from the anesthetic, but I couldn't bring myself to do it.  Then felt bad about it.  Then felt bad for feeling bad.  I know I'll have to make that choice soon, but right now he's not in pain, he's not visibly sick, he loves playing, he eats as if food is being rationed tomorrow... who am I to cut short a life? No, definitely not a good place.  Sorry.
