my cat, in the year and 3 months that i have had her, has almost NEVER eaten human food. she will not touch anything that is not made specifically for a cat, oddly. will almost never play with anything that isn't a designated cat toy (with a few exceptions). she will not eat anything other than cat food or cat treats, but loves each of those fervently. she will only eat one brand of cat food (alley cat). the only exception to this rule is plants.
