Rabbit Behavior Definition | |
---|---|
Rearing | Animal is up on both hind legs and torso is perpendicular to the floor |
Grooming | Animal is licking or scratching its coat or face |
Hopping | Animal is moving forward by pushing hindlimbs followed by forelimbs |
Lying down | Animal is in a horizontal position on an elevated platform |
Chewing | Animal is actively biting on non-food material |
Burrowing | Animal is using forepaws to dig into the bedding material and to scratch on the floor of the pen |
Eating | Animal is biting and swallowing food |
Drinking | Animal is consuming water |
Exploration | Animal is actively moving around, jumping, and sniffing on enrichment material |
Hiding | Animal is sitting/lying under or behind tent/tube/platform or opaque wall element |
Fighting | Animal is biting, chasing, mounting, or snapping at other rabbits |
Other | Animal performs other behavioral patterns than those stated above. The value is calculated as the difference of all measured behaviors from the overall time of observation |
