I'm glad to know that, too. I was sitting here with this dreadful fear after what I read.
I found this, too:
Avocado leaves - Cases of avocado poisoning are seen periodically in Los Angeles County animals. Commercial production of avocados is located primarily in southern California and Florida. Two types of avocados are grown in California (Mexican and Guatemalan) and toxicity varies. Toxicity may also vary depending upon the time of year and other factors that are poorly understood. Various species of animals are susceptible to avocado poisoning. Dried avocado seed can kill mice.
