Susanne,
Sorry to hear about your FS0.
My longest relationship with a cat was with Minnie Meowse, who succumbed to kidney and other internal organ failure at age 17 3 years ago. My new kitty, Melanie La Mew, is great, but I still miss Minnie.
Do all your cats write song? Maybe, if you have a new one, he/she can write more verses?
