Stealth, what is a bearcat? Do you have pictures?
My previous cat, "B" (R.I.P. little buddy) had wide ranging tastes. He shared a bit of Hot Sour Soup once. He loved BBQ, especially BBQ spareribs - with sauce; and BBQ salmon & halibut. REALLY liked shrimp, scallops too - but had a built-in "fresh-ometer" and wouldn't touch them if they weren't really really fresh. I am amazed at the other cats represented here who eat fruit and veggies - these held no interest for "B," although he did enjoy dry brewer's yeast powder. Very much. I never got to try him with vegemite or marmite, both of which are in the 'fridge. I may be wrong on this, but my understanding is that cats are not well-equipped to deal with sugars, and a diet with a lot of sugar can result in diabetes for a cat easier than it would for a monkey-boy. If this is true, I would limit the sugar to a little bit once in a great hile, taking into consideration that our cats are between 1/20 and 1/10 our size.
After "B," "C" moved in. "C" follows a spartan diet of his own choosing. He has no interest in any of the things that "B" enjoyed so much. Mostly his diet is dry food, with one can of wet food at night. I add a can of hot water to his wet food to make it more "soupy" for him. He likes that, and the superhydration is good for him (to avoid boy-cat troubles). He likes some occasional halibut, but not on a regular basis. Won't touch dairy - no cream, milk, anything. No beef, no pork, not even chicken. I'm always looking for new things to offer him, but food is not his main interest. POWER is his thing, I think. I'll try some vegemite on him tonight, but I expect he'll say "no, thank you very much."
