Why Avocados Are Bad for Birds

Foods that taste delicious to humans can be poisonous to animals. The avocado is one of those toxic fruits due to chemicals in the skin and pit, though they are not found in the fruit itself.
  1. Toxins

    • The toxin that dwells in avocados is called persin. It is a polyketide chemical that, while perfectly safe for humans, is incredibly toxic for animals.

    Reactions

    • Persin causes cardiac problems in birds. This can start with breathing problems, followed by heart failure and then, the very unpleasant and sudden death. Sometimes the persin only causes irritation for birds but there is no guarantee this will be the only reaction.

    Other Dangers

    • Avocado is not simply dangerous to birds. Rabbits, horses, dogs and cats are all susceptible to the toxins. While the persin is not in the fruit of the avocado itself, the chemicals can easily seep through the skin or pit into the flesh of the avocado. The safest option for your pets is to refrain from feeding them avocado.

    Fun Fact

    • Studies are showing that persin may kill breast cancer cells when combined with breast cancer medication.
