Bitey, I just googled around a little and it seems to me birds, goats and dogs are the only thing most websites talk about. Kind of interesting though! I guess the guy that wrote the article had damaged his kidneys from consuming too many avocados. I never would have guessed that!
"Avocados. The leaves, fruit, bark and seeds of avocados have
all been reported to be toxic. The toxic component in the avocado is "persin,"
which is a fatty acid derivative. Symptoms of toxicity include difficulty
breathing, abdominal enlargement, abnormal fluid accumulations in the chest,
abdomen and sac around the heart. The amount that needs to be ingested to cause
signs is unknown. Do not feed your pet any component of the avocado."
