I DID NOT suggest shining this at any animal, only using it as a
directional pointer. Michael Price made the excellent point of not
trying to use this tool in a crowd. For any possibility of damage
(which is pretty remote) the laser/light must be focused directly on the
eye at a pretty small range of angles - this is not one of those the
light is so intense it will blind you if you look at it things.
If you don't think you can use the tool safely then don't do it. It is
however an excellent method of indicating general proximity.

There's probably a lot less risk to animals when using this tool
properly than there is to animals from your automobile on the trip to
see them - or feeding them in poorly maintained spaces (re: the
salmonella thread), or study casualties, etc.

Then there are always the incidents of binocular fires...nice sunny day,
stretch out, put binocs down, focus that light and poof!
