When your bunny gets a cut, it is no small matter.
Bunnies have a very serious reaction to cuts and other wounds.
In many cases, when a foreign body enters a bunny's body, it is encapsulated. The bacteria from the foreign agent react with the bunny's own antibodies, creating the thick creamy gunk that fills an abscess capsule. Unlike other animals, including humans, bunnies do not simply reject the foreign antibody and expel it. Sometimes a very small, very simple wound can end up endangering a bunny's life. Make sure any cuts are cleaned and disinfected thoroughly.
