Something is eating bites out of fresh fruit in my house at night. I
have five cats so I can't believe it's a rodent.  Any suggestions?

It depends on where you place your fruits. Because even though you
have five alert felines, if a rodent is positioned in a spot where any
of the cats can't reach it while it gnaws away at the fruit, it has to
be a rodent. Otherwise, roaches are the most likely cause.

Probably the best way to find out is to put a camera to cover the
"scene of the crime" so you can positively ID who or what actually is
the culprit.

It's possible that one of the cats is the culprit. Some cats find
fruit attractive. We once had an orange tabby who would gnaw holes in
bananas.

We'd actually thought of the camera idea.  Our cats can definately
reach the kitchen table where the fruit is sitting in a bowl.  This
creature seems to prefer pears.  Doesn't eat apples or bananas!  It
looks like it was eaten by something with teeth so don't think it's
roaches.

We'd also thought of the possibilty of a bat coming in down the
chimney.  The cats would have a harder time catching them and some
bats are fruit eaters.

My mother has a cat who eats bananas, and I've seen other cats eat
peaches...I think a camera is the best bet!

The bat coming down the chimney is an interesting possibility, but if
that happened, I doubt that the bat would be able to find his way back
up the chimney. I doubt that bats are that intelligent.

A raccoon could certainly do it, though. Years ago, a friend of mine
had a lakeside cabin that was invaded by a raccoon who came down the
chimney, pigged out on the food (even raiding the refrigerator and
drinking half a can of beer), and left the way he'd come in. This
happened every night for weeks, and only by using a video camera did
my friend solve the mystery. A screen covering for the top of the
chimney kept the raccoon from continuing to invite himself to dinner.
