Yes, rabbits can eat radishes in moderation. They have a bunch of nutrients that make them beneficial to rabbits, but they’re also acidic and high in carbohydrates so it’s important to limit the radish portion your rabbit eats.
An ideal portion for your rabbit is two tablespoons of radish, once or twice per week. With no cholesterol content, no fat, and hardly any calories, radishes are like a super-food for rabbits.
