Figured this out last night. I'm a mage and my hunter friend was trying to get a pet from the temple. He couldn't get it cause it kept interrupting him.

Using polymorph though he was able to easliy tame the creature without danger of being interrupted. Just have the mage poly the creature and go to town making your cute little hearts and getting your pet.

Also if you're having problems and dont have the assistance of a mage, pull the creature into a freezing trap to buy yourself a little more time.
