Ah, go back to your home and take the Raptor with you from the animal screen after clicking on the hammer icon next to the potion icon, it should be a brown squirrel on the screen where you see the building items and a pot as well on the left side, you need to have him as a companion to take with you on your journey to turn him in to the Witch, note, after you do this, you need to capture him again if you want to use him as a companion, he keeps whatever progress he gained from training with him, he needs meats to feed his energy just like the dog does.
