Rabbits Perform An Athletic Leap, Known As A ‘Binky‘, When They’re Happy
A rabbit should not be kept in a cage or hutch for any more reason than a dog or cat should not be kept inside of a cage. Because they are curious creatures, rabbits require a lot of enrichment to exhibit their natural behaviors and keep their minds active. In order to run, investigate, explore, and dig, they require a lot of space (in a safe and secure yard), as well as toys to play with and gnaw on.
Despite their reputation for being quiet, bunnies are constantly expressing themselves. Unfortunately, a lot of individuals are simply not very good at "reading" body language. A "binky" is a rabbit's springing into the air and flicking out its back legs as a sign of joy. To alert their loved ones to danger or to convey their wrath, they may thud their feet. Additionally, they have a variety of vocalizations, albeit they tend to communicate more frequently through body language.
For instance, if you're particularly fortunate, a rabbit may run about you while emitting a low humming noise as a sign of their liking. They may grunt at you to tell you to leave, and males may 'honk', especially if they haven't been neutered. A piercing cry indicates intense pain or suffering.
