I'm so sorry for your loss. Ozzie sounds like a great kitty.
Less than a month after Kuhio's death (1985-2002), we adopted Halo. Some people are shocked by that but we found comfort in giving another homeless baby a forever home. You'll know when the time is right to pass on all the love Ozzie taught you. To me, the only thing sadder than losing Kuhio would to have never loved another. I wouldn't be surprised if Ozzie didn't send another baby that needs you desperately. He knows what a wonderful, loving home you can provide.
