If you’re wondering if your rabbit can eat avocado, the leaves from an avocado, or the skin, the answer is NO. Avocado is one of the foods that are toxic for them, as they are for a lot of animals.
Avocado contains toxins that are harmful to a lot of animals, the toxin is called persin. It only effects certain animals, and rabbits fall under this category. I will repeat for the sake of safety, do not let your rabbits eat any part of the avocado or the plant, which includes the skin and leaves.
You should be providing a diet consisting mostly of Timothy Hay, rabbit pellets, and some leafy greens. This along with plenty of water and the occasional treat will keep your rabbit healthy and happy.
If you think your pet has eaten something that has disagreed with them seek professional help as soon as possible. As a responsible owner you can’t just throw any food or leftovers in their cage. Monitor everything they have access to as they have fragile digestive systems.
