Thank you everyone! Seems like a silly question now, but I'm a worrier.
The only good thing about having him is when I take one of the girls out to work with, the other one has him for company and they don't worry about who's out. With only two I'm sure they'll be a little worried about being left alone when the other is out working, but we'll see. I feel terrible because I am attached to the little bugger, but just having the two would be so much easier.
