So sorry for your loss.
In past years, we heard a sorrowful sound and my Lizzy found a kitten, so small it was curled in the palm of a 12 year old girl. Named Jelly Bean due to the visual of this. hand nursed with a dropper, he grew into the Best Cat. After 11 years he developed kidney failure and wasted away over 4 or 5 weeks. He was hand fed and given injected hydration until he found the treatment very painful, and could not even eat. He was held by me , Bridget and comforted as best we could until he died in his blanket. He seemed relatively comfortable and purred while being held, until his end, last week. He had a viewing for his 3 cat companions and was buried in the door yard. I am sad.
