These guys are GREAT!!!!!! They seem very responsible and I think this just may be the perfect home for Lucky and Chance! Here is a portion of the email he just sent me:

I have a pet door idea that I may have to invent if I can't find one already made. You probably know about the pet doors that only open if the animal is wearing a collar with the right radio frequency. These are a great idea for keeping other animals out, but the problem with trying to keep cats in is that the cats just learn to follow the dog out. What I'd like to find is one that comes with 2 types of transmitters-- one that opens the door, and one that locks it (where lock overrides open). You put
the open collar on the dog, and the lock collar on the cat. That way, if the cat is following the dog, the door won't open for either, but if the dog is at the door alone, it will open.
