There was a certain part of this movie I thought was quite entertaining, and thanks to youtube, can display the pertinent part:

The first part of the pair was the one of which I was thinking with the situation tonight. We have Tweety bird, and Jake the cat. Jake has an interest in Tweety the end of which would not make a certain mominbox appreciative of his efforts. That being the case, we have to maintain a distance between the animals. This has mostly been done with a shut door or just holding Jake while in the room where Tweety resides – (living room). To make matters easier on the humans involved, we purchased a harness and leash which fit nicely around the table leg. Jake was attached and instantly assumed the position most logical for a cat – facing Tweety at the full extent of the leash. I can almost read his mind, “dang force field!”
