What is an abscess in rabbits?

An abscess in rabbits is characterized by a hard swelling or a collection of pus, typically occurring due to a localized infection. This condition arises when bacteria invade the skin or underlying tissues, leading to an accumulation of pus as the body responds to the infection. The formation of abscesses can occur anywhere in a rabbit's body but is most commonly found under the skin, in the mouth, or in other soft tissues.

The context of other options helps clarify the definition further. While a skin infection can lead to an abscess, not all skin infections result in this condition, making it less specific than the correct choice. An internal organ malfunction refers to broader issues unrelated to the localized pus collection seen in abscesses. Similarly, a common respiratory disease would pertain to conditions affecting the respiratory system, rather than the localized swelling and pus accumulation that define an abscess. Thus, recognizing the primary feature of an abscess as a hard swelling or pus collection is crucial in understanding rabbit health and treating such conditions effectively.
