Hey Guys. I just wanted to know, how does changing the diet of your pet affect anything? I've heard that it affects the proportion in which the food food you have in your inventory is used up but does changing it have any other effects?

Pet diet affects the probability of certain characteristics to be raised with level up. You can hover over (?) sign near the "Diet Composition" title to learn what characteristics do different types of food increase.

 thanks, Angel. :D
