I'm sorry about your loss. I sometimes include Pepper when I do the Companion Animal Memorial service Monday nights. I think rabbits are fairly long-lived as herbivorous animal companions go, but 9-12 years is normally the most you can hope for. (Parrots are very long-lived, of course, and there are parrot rescue/adoption organizations... but as you know, they present a different problem: they sometimes outlive their human caretaker. And frankly, if a rescue parrot had behavioral issues from being treated badly, I don't know if I would be able to handle the bird... not if s/he was intent on maiming me anyway.)
