I always took in Cats so that they would be Found Cats , and I know that I would be a failure at fostering as the Found Ctas and I would not have wanted them to go. Raganar Guftason the Maine Coon would have stayed but he had a devoted owner in the wings.
And Ebony Beau Tubster and Gem and Charcoal would have been Found Cats , but fate and FIP dictated otherwise!!
