I know what you mean as I would have loved to keep Tubster, Scout , Gary , Elizabeth , The Tabby Cat whose name I forget, and Scratchier.
All are doing well in Foster Homes, as at my agr and health, I am at the limit for New Cats.
You have to be pleased that you got Sprocket a fine New Home with someone who will love and cherish him.
Ragnar was one I really wanted too, he was a Bear Of A Cat with a heart of gold.
But we cant keep them all, we have to share the love.
Great News, and Bless You for helping Sprocket.
