"My question is, say I feed the gator more than one food item at a time, should I put the supplement on all the items or just one."
Really, it depends. What is the other food item? Are they both the same thing? What is the other food items value in calcium?
"I am feeding every 2 days right now so should I still supplement every other feeding?"
There's nothing wrong with supplementing every other feeding. Just make sure that you are keeping in mind the food items current nutritional value without the supplementation so you know whether you should supplement or not. If it is a whole prey item (minus pinkies of course), then supplementation is not necessary. Only supplement if you are feeding chunk meats, etc without bone. Whole prey should be fine.
"Do I use the multivitamin as often as the calcium or one more than the other?"
I recommend using them both simultaneously. Although, in reality...Calcium is your most important supplement. The multivitamin isn't necessarily an imperative item to provide as long as you are feeding a good variety to the animal. If you are sticking with Chicken breast and beef chunks as it's primary diet...then yes, use both often. Otherwise, Calcium is the most important component.
"Have you ever fed shrimp to gators are there any dangers?"
From what I read, shrimp carries thiaminase in pretty decent amounts. I would avoid it. Whenever in doubt...don't do it.
With that being said, I would have to second Bert's (Kachunga) post. Mazuri diet is simply the best way to go if you want to alleviate the hassles of determining a good diet plan for your animal. It's simple, reasonably priced, and complete nutrition. Almost sounds too good to be true...but it is
. It's only downfall is the mess that the animal leaves behind from crushed pellets and defecation. Be prepared for more frequent water changes!
