I am very sorry to hear that Teddy. I am sure he is at peace now, know that you did your best for him.
I found this, I hope it helps.
And God asked the feline spirit,
"Are you ready to come home?"
"Oh, yes, quite so," replied the precious soul,
"And, as a cat, you know I am most able to decide anything for myself."
"Are you coming then?" asked God.
"Soon," replied the whiskered angel,
"But I must come slowly, for my human friends are troubled
For, you see, they need me, quite certainly."
"But don't they understand?" asked God, "That you'll never leave them?
That your souls are intertwined. For all eternity?
That nothing is created or destroyed? It just is....forever and ever and ever."
"Eventually they will understand," replied the glorious cat,
"For I will whisper into their hearts that I am always with them,
I just am....forever and ever and ever."
