Yes, rabbits can eat radishes in moderation. Radishes are a safe and healthy treat for rabbits as they are low in calories and high in fiber, vitamin C, and other essential vitamins and minerals. However, it is important to feed radishes to rabbits in moderation, as too many can cause digestive upset and other health problems. It is also recommended to introduce radishes to your rabbit's diet gradually and monitor their reaction to it. Some rabbits may not like the taste of radishes or may be allergic to them. Additionally, make sure to wash radishes thoroughly before feeding them to your rabbit to remove any dirt or pesticides.
