So every night when we go to bed, I give bunnies a bit of dried papaya to get them in their pen. Once they began to understand the connection of night time=papaya treat, they started getting excited every time I stood up at night and head binkying and running around in circles. They still do this, but then they learned that the *click* sound that my boyfriend’s sound system makes when we turn off the speakers means that papaya is definitely about to happen and they start binkying and racing around and running into each other. They still do this too… accidental clicker training. But it gets even more ridiculous, the past few weeks my boyfriend and I have been watching Buffy the Vampire slayer pretty much every night before bed… and now they start to run and around and binky whenever they hear the Buffy closing credit theme music! I’ve Buffy trained my bunnies! 
So smart! Bunnies really aren’t just cute like everybody supposes…
