Diarrhea: Apples contain a lot of fiber, which can be helpful in small amounts, but too much fiber can cause diarrhea.
Gas: Apples also contain a lot of sugar, which can ferment in the rabbit’s stomach and cause gas.
Stomach upset: Apples are acidic and can cause stomach upset in rabbits.
Weight gain: Apples are high in calories and can contribute to weight gain if fed to rabbits in large amounts.
Malocclusion: Apples are hard and can cause the rabbit’s teeth to become misaligned, which is known as malocclusion.
If you are concerned that your rabbit has eaten too many apples, it is important to take them to a veterinarian immediately.
