The food I fed my last cat was multi-colored. Each morsel was a different color and a different taste. First he'd sit and stare at the bowl like it was the most wonderful thing he'd ever seen. Then he'd pick up each piece with his paw pads, contemplate the absolute magnificence of it and then he'd eat it. This would happen with 5-6 pieces and then he'd fall upon the feast like he hadn't eaten in three weeks, wolfing it down.
Then he stopped eating. He'd come in, look at his food, turn his nose up and wander off. He might be tempted by a morsel of tuna or a little ham, but mostly there was no interest. I was worried about him but he wasn't losing weight (actually he was getting fat) and he didn't look sick, so I thought I'd just hold off for a while and see what was going on.
After a few days, I came home from work and the animal services van was in front of my house. The guy got out and said he wanted to talk to me about my cat. MY cat? Yes, MY cat.
Apparently, an elderly neighbor two houses down had made a complaint that I wasn't feeding the cat. I showed the guy that there was a cat door and that there was always food and water available. I said, let's go talk to the lady.
The elderly lady said she had been feeding him because he was "soooo hungry" and was acting like he wasn't getting anything to eat. He just begged and begged, she said. What was she feeding him? Oh, she was feeding him cream and tuna and fish and chopped liver and..... She was told to stop feeding him, that he had adequate food at home.
That sh!thead cat was gaming both of us. I'm pretty sure she was still slipping him a few treats but he did start coming home for dinner.
