I don't know! There is no way they could get in from where the one
disappeared up on the roof. Any openings have been sealed (soffet
around the front door was the only place birds or squirrels could get
in before) but it's been a long time since I've even looked in the
attic. Good thinking though. I guess I better have someone check it
out.

I know! Many years ago I took in a mother cat and her 3 newborns.
When the kittens were about 2 months old, I started having lots of
fun with them. I can remember doing stuff like sitting on my bed
with a pen in my hand, waving it around in the air. The 3 of them
would sit on the floor in front of me, their heads going back and
forth in unison as they watched the pen move around. Hilarious!

suppose that could well be the case. Last fall the squirrels
discovered a knothole in the cedar siding on our apartment building
and commenced stocking pecans for the winter. Sammy and Little Bit
started spending a lot of time by my kitchen window, the closest to
the new nest. I really don't think they could see anything, except the
squirrel coming and going, but they could sure tell something was
going on. Our landlord had a devil of a time stopping the squirrels
from taking up residence. He covered up the one hole they were using
with a piece of sheet metal. But the squirrels had figured out how to
enter through knotholes, and as soon the landlord covered one they'd
move on to the next - stubborn little critters. Ended up with the
landlord spending two or three days going around the two two-story
buildings covering knotholes with metal and stuffing steel wool in
cracks.
