Zipper was litter train as a kitten but since she's an outdoor cat she
does her business in the bushes.  Since the temperature gone below
freezing I started having her sleep with me.  As soon as she gets out
of bed I would let her out.  A few times she got up before I did and
started looking for food.  I'm just wondering if some day I'll be
surprised by finding turd & pee in a closet or under furniture.  I
have no idea where she does it outdoors and am afraid she might do it
indoors at an out of the way place without my knowledge.  So far I
don't smell anything.

She's about 9 months and haven't used a litter box for 5 or 6 months
now.  I just hope it's normal that she don't have to go for 10 to 12
hours.

She likes to curl up near my legs for the night.  When I move her near
my chest she'll purr for a minute and than goes back to the foot of
the bed.  If I bug her too much, she'll get off the bed and go sleep
on a chair in the next room.
