Can rabbits eat oranges?
Some rabbits like oranges but they should only be a fed very small amount as an occasional treat because they are high in sugar. Feeding rabbits treats that are high in sugar and starch (carbohydrates) can cause bad bacteria in the digestive system to outgrow good bacteria which leads to diarrhea and death. You may also notice that it will cause your rabbit to become bloated.
In the wild rabbits eat a really high fiber diet that is very low in carbohydrates. This makes it so that the bacteria in their digestive tract have to work hard to ferment the food a rabbit eats. It ensures that only good bacteria grow and provide the nutrients that rabbits need. For this reason the main diet of a rabbit should be pellets that are properly formulated to meet their nutritional needs based upon their age.
For example, baby rabbits need a high fat diet (like mamma's milk) while adult pet rabbits will be healthiest eating pellets that are grain-free and soy-free but rich in grass hay (like timothy hay) and balanced with the right vitamins and minerals.
So, can rabbits eat oranges? Yes but only as a small treat!
