It's no secret that animals are smart -- some are really smart -- they've even co-opted technology for their own benefit. Here are some of the most incredible examples:
1. Crows that use cars as their personal nutcrackers
2. Stressed out cat just wants to relax with a neck massage
4. Birds use automatic doors to access their secret underground lair
5. Cat uses an iPad to practice hunting
6. Dog lets vacuum cleaner do his bidding
