Whoever did this is a complete idiot. Hiding the bells won't help, those cats are going to go outside and find their own bells and bring them inside. They're going to be hearing bells for the rest of their life, including at 2:00AM when the cats wake up and pull a hidden bell out. I do like the brown cat trying to ring both bells at once though.
Handedness is actually something almost all animals have. From the studies I've read, rather than the advantage ambidexterity is in games, it's actually a weakness in surviving. Having a dominant preference side means that when you need to move reflexively, your body automatically goes in that direction instead of pausing to decide which way is better. The fraction of a second this saves can be a lifesaver when a big predator is pouncing at you.I'm just amazed that A: You can train cats to ring a bell
B: Cats have handedness just like Humans do
C: They're only ringing the bell once, instead of wailing on it until their treats are delivered.
