Input: Text: my wife and i have an adorable, incredibly active springer spaniel puppy named marlin. he's a really great dog, but he's really obsessive. we also have two cats named buster and posey (we are big giants fans). a couple of months ago i pulled out the cat-toy laser-pointer, which our cats are usually fairly indifferent towards. i was just trying to get buster to play a little, but it sent marlin into a frenzy.

at first, it was funny. the good bird dog that he is, he would chase that thing everywhere we shone it until we got bored. seriously... we would get bored before he did.

we are both really busy; so i would start to use it to exercise marlin. i could stand in one place, cocktail in hand, and run the dog ragged. i thought this cat laser was a godsend. this is where i fu.

now marlin chases anything that resembles a shining light. his dog tags gleaming in the sunlight: chase-paw-bite-bark. a reflection off of our cell phones onto the floor: he'll fly out of his chair and start sprinting toward where the reflection was. even a neighbor's headlight flashing through our living room window will literally wake this dude up and put him on high alert. he was never like this before i inadvertently got him hooked on a cat laser. now he treats any shining light like a fat girl treats cake.
