Anthropomorphic Animal

You transform the touched animal into a bipedal hybrid of its original form with a humanoid form, similar to how a lycanthrope’s hybrid form is a mix of a humanoid and animal form. The animal’s size, type, and ability scores do not change. One pair of its limbs is able to manipulate objects and weapons as well as human hands do; limbless animals like snakes temporarily grow a pair of arms. The creature’s Intelligence increases to 8, and it gains the ability to speak one language you know. It is not considered proficient in any manufactured weapons. It can attack with unarmed strikes.

The duration is [your level] hours

Anthropomorphic animal can be made permanent by casting this spell on a animal already affected, replacing the material component with diamond dust worth at least 7,500 gp (which the spell consumes).
