Avocado is a fruit full of nutrition, but its leaves, skin, and seeds contain many harmful chemicals. Astonishingly, the juicy part of the fruit has fewer chemicals. Avocados also contain a lot of fat. Yet, rabbits cannot handle grease. Research links high-fat diets to rabbits that are overweight. Hence, some rabbits may react badly to it. Moreover, avocados have more carbohydrates and less fiber. Food rich in carbohydrates can cause enteritis, GI stasis, and diarrhea in rabbits. Therefore, even a small amount of avocado can make your rabbit sick.
