Growing Avocado

Less than a month ago after eating a store bought avocado, the hard avocado seed was buried into a very small tub of soil where our three surviving cacti dwell.

In just a few short weeks, we have this unexpected surprise:

It's only about an inch tall, has some very tiny leaves/branch buds close against it's stem. We're going to have to re-pot because if it keeps growing, it's roots will most likely suffocate the roots of the cacti.

I don't know much about growing avocado's, but it would be cool if this grew into a tree with new avocados for me to eat!
