The attack stat represents how much damage the animal was inflicting on my monk (from a mean average of 10 values).
the defence stat represents how much damage my monk inflicted on the animals (again, on an average of 10).
ROA means Rate of Attack.
What we can tell from this data is not alot really, since all the animals in the wild start at different levels, making it hard to deduce if they're any differences between them at all, but hopefully this should at least get the ball rolling on having a collection of useful information about pets.
