Targets for Beast Lore

You can use Beast Lore on any creature which is not of the Humanoid type.

If a non-Humanoid took this ability, I would consider changing it to "any creature not of your type", but keep in mind that this basically gives any highly intelligent monster the ability to give itself and all its allies a +1 bonus to attack and damage vs all the player characters, more or less all the time.

House-ruling the ability to work on any type of creature is an option, but the feat's effectiveness may be radically increased if the campaign uses a lot of humanoid opponents.
