Congratulations, Rob!! SD retics are awesome. My girl is incredibly friendly too, but watch the feeding response. Retics of all sizes are known for a ravenous, fast feeding response. For example, my girl Baby can be handled and trusted with just about anybody once she is out of the cage, but if there is food around forget it. Sunday I fed them and I had Baby's large rat dangling on the tongs right in front of her cage when I opened the door, but she flew out right past it and bit the floor. It took 10 minutes to get her face out of the carpet, as she was actually trying to wrap the floor!!! Another time she latched onto the radiator. lol. If there is no food in the room though, she is a total puppy dog.
Best of luck with the new fellow, I'm sure you'll be looking for another one in no time. Retics are special.
