I probably go a little overboard, but I like to have variety in Bandit's food. I stick to the same two brands (Merricks' and Fancy Feast), but I do get a lot of flavors between them. Probably about 4 different flavors for Merricks, and 5 or six different flavors of Fancy Feast (Yes, that's 9-10 different flavors in my cupboard :smile: ). The Fancy feast only comes out a few times a week, so for the most part I rotate between the Merrick's flavors (Cowboy Cookout, Surf & Turf, and either Grammy's Pot pie or Turducken).
I think it's a mental thing leftover from when I was treating Gabby's stomach cancer--she would get sick of things so quick I had to be able to pull a different flavor out for her often, and Bandit would of course get the remainder of her cans so it didn't go to waste (as long as they were low carb). I would keep a variety of all different brands of food, so I would say there was probably about 20-30 different flavors in my cupboard back then. So even though I can count the times on one hand that Bandit has ever refused food in his life, I guess I keep a variety to guarantee I have choices to coax him to eat if I ever have to.
Mainly, though, I think it's preference thing for me--I wouldn't want to eat the same thing all the time, so I transfer that to Bandit--even though I'm pretty sure he doesn't even taste the food as he gobbles it down, so I highly doubt he can distinguish between foods. His mental process is more like "food!food!food!" and not "The lobster in this Surf and Turf entree adds such a delicate seafood flavor to the beef in the Cowboy cookout."
