Query: Boat Kitty Loves This Bad Boy!

I installed one of these in my houseboat and it is amazing. I did it on training mode for a few weeks (no batteries) until the neighbor's cat figured it out. I went down to the local vet and got a microchip immediately and now my cat is zipping in and out with no problem. At night I just set it to no in and out so he stays inside. When the neighbor's kitty tries to infiltrate our solitude we just laugh at him ... as he is no match for this kitty door. **update: I was wrong. The neighbors cat is now lounging on my couch and there is an empty bowl in the kitchen. Buy knowing that this is not fool proof after all.
