Tiger is gone. He was pretty miserable, so my brother gave me a ride to the urgent care vet took care of him.
He went peacefully. i’m so sad, but it had to be done. Many thanks to everyone here who cared and help me get through this.

I am so, so sorry for the loss of your precious Tiger. I know the pain is unbearable. 💔
I extend to you my deepest sympathy. 
RIP Tiger. You were truly loved.
Healing vibes on the way to your heart.
You gave him love and you did right by him. That is what counts.
Tiger. He is now resting in peace, and I hope that you will also find peace in knowing he is out of pain.
Sometimes choosing to end a pet's suffering is truly an act of love and compassion. I have been there a few times myself
Hugs to you, dear Walleye. You're in my thoughts.
I'm so very sorry.
I know you'll honor him in your thoughts, you'll keep him close with your memories, and your love for him will never die.
How lucky are we to be given such a wonderful burden, the care and well being of a kitty as special as ours.
He chose you and clearly chose well my friend as you've been his lifemate for sixteen amazing years now.
With each wave of pain and grief, I'm only comforted by the waves of individual memories that no one can ever take away.
Please let your tears flow, as we are never to old to feel sad, please say every word to him that comes to mind, because it's never to late to give life to your feelings, and please love him tonight, the same wonderful way you have for the last sixteen years.
Oh God Walleye, I know your pain my friend. Please don't run from it.
Love, John
Knowing it’s time to let go does not mean it is an easy decision to make, nor that it hurts any less to see your loved one go.
May your happy memories with him ease your sadness.
...agonizingly difficult.
Maybe I said this here already. In our family, we call this "liberating the spirit." Tiger's spirit is now free.
