Mila is bananas over bananas, popcorn, yogurt, salmon and cheese of any sort, including soft cheeses with mold rinds, which shocks me a bit. Pretty much anything but a few select veggies, like carrots or green beans.
My cat on the other hand, will turn up her nose at seafood and poultry of any sort, but loves ham, mayo, donuts, bread and chocolate* (and only good chocolate; it has to be Godiva, Vosges, Ghiradelli...nothing beneath Cadbury or else she huffs away in a snoot. "I would never deign to eat Hershey's! What do you think I am, a street urchin?!").
*no worries, I only give her chocolate very occassionally and in infintesimally small amounts. Nothing to put her in any amount of danger.
