Once in while, (rarely, but once in a while), I surrender the high ground to Fritz.
He is older than me after all, so it helps him to feel "in charge", and that makes him more easy-going in the long-run. I haven't told him yet that it's all calculated on my part: really, I'm in charge when he thinks he is. If he feels dominant, he's happy.
Mind you, the Feeders do point out to me ocassionally that I'm really wasting my time with my covert operations because, frankly, Fritz doesn't really mind as long as he gets his food and Feeders' love, and that he will countanance anything I do just as long as the food and love keeps flowing.
Mainly though, as long as the Kitty Cat Cafe is always open for Fritz, he's a happy camper, and happy to let me feel in charge.
