Other then reading books is there another way of raising my pets Intelligence ? I am running out of affordable books to buy. Thank you

There are stat boosters, they all do different things! Here's an old thread that explains them. >Guide to Stat Boosters< Although it's no longer being updated and seems to be past the necro time limit.

Thank You :)

Mystic Spindles also rewards points that you can use to purchase intelligence - but it gets increasingly expensive and is a more viable option prior to mass reading. (For what it's worth, there's a handful of books purchased by way of those points, also)
