This is so true! I catsit for a friend when she is on vacation. She always leaves me detailed instructions on when, where and which food to feed each of her cats. Her tortie,Musette, has one set of rules for her owner and a completely different set of rules for me. I’ve learned to ignore the instructions and feed her on the second level of the cat tree in the hall. She will only accept Fancy Feast or tuna served on a saucer. Any deviation from that location, menu or dish and she will follow me around the house, loudly complaining.
