Today I learned that rabbits, as well as cows, don’t digest grass directly. While cows use their stomachs to get the grass eaten up by bacteria that is afterwards digested by the cow itself, rabbits don’t have the luxury of many stomachs. Instead they produce a special kind of faeces after eating the grass for the first time, that allows them to digest it at the second time, after eating those faeces. This process is called coprophagy.
And if you wonder how I came up with this topic, it was just a casual talk about this blog, curious every-day-knowledge and rabbits. Obviously you can find a lot more about this topic on Wikipedia.
