Re: *MY FURBABiES ..
Oh! What sweet kitties, and I'm so sorry you lost a kitty to FIP. How awful to lose Savvy to that, and so recent. I'm sorry, please accept my condolences. She looked beautiful.
Welcome to CF.
Husband and I have had a Trio of cats (2 bros, 1 sis) from the same litter. We also caught their father and retired him from a feral farm cat to a housecat when he broke his leg. We also took in two more cats that I called "cousin cats" because the family resemblance was so strong, but we didn't know exactly how they were related. Anyhow, The Trio were always VERY close and we loved watching them interact with each other. They ate, played, slept and wrestled together. You could definitely tell they were much, MUCH, more comfortable with each other than with any of the other numerous housecats (between 6-12 at times). I know exactly what you mean when you describe how your Cupid and Domino are.
