* Rabbits: Rabbits are herbivores and their digestive systems are designed for grasses, hay, and leafy greens. Oranges are high in sugar and citric acid, which can cause digestive upset, diarrhea, and even urinary tract issues in rabbits.
* Squirrels: Squirrels are omnivores, but their primary food sources are nuts, seeds, and insects. While they might be attracted to the sweetness of oranges, the high acidity can be harmful.
Important Note: It's best to avoid giving oranges to both rabbits and squirrels, as the potential risks outweigh any potential benefits. Stick to their natural diets for their health and well-being.
