Probably make them hyper and eat even more.  :)

My concern would be the effect on frogs and/or toads in the yard.  If
I remember correctly, amphibians are severely affected by caffeine as
well.  

In Hawai'i the coqui (a small frog that used to only be found on Puerto
Rico and makes a lot of noise at night) problem was originally going to
be controlled by caffeine sprays into foliage.  The caffeine increases
their heart rates by affecting a neurotransmitter in their brains,
eventually causing death.

Regular strength coffee may be a non-issue -- I have no idea what
concentrations of caffeine are needed.

But what I really want to know is...  What's left-over coffee?  Never
seems to be a problem around here.  :)
