Mary, it is so difficult to see our cats grow old, losing hearing, eyesight and perhaps getting senile. It may well be that Boo misses Pigeon and of course Boo can't understand where she has gone. Give him as much love as you can. I'm sending lots of good thoughts to your dear Boo.

Fister is also walking through the rooms at night miawing, but he will come up to me in bed and lay down beside me. I guess he is telling me that just saw a stray cat in the yard.
