Our cats are having the same issue! I thought it was just me I have been trolling the internet trying to find someone else that’s having this problem too! I thought it was the food, I love this food I don’t want to have to change it. Do you know if the ziwi brand cat food has any preservatives in it? Because that’s why I love FN no preservatives no garbage nothing and it’s lightly cooked .

Hi Amy, that’s a good point. We will investigate further and see what we can do to provide some more insight into what this reading means.

Hi Barbara, we edited our list of the best food for hyperthyroidism to only include low-iodine foods, and the Feline Natural recipe didn’t make the cut. Previously, the list was focused on including a variety of foods that would support overall health in cats who were already being properly treated for their thyroid issues. Since the update, we’ve done extensive research to seek out iodine content from each candidate and narrowed the list down significantly. The reason we don’t have more choices for dietary management of this very common condition, I think, is because the amount of dietary iodine that it takes to control hyperthyroidism is so low that it makes the food no longer nutritionally complete. According to AAFCO guidelines, the one hyperthyroidism food on the market (from Hill’s) is a nutritionally deficient diet. Hence, in part, the “prescription” status—if it were available to anyone without a vet’s approval, they’d be feeding their cats nutritionally inadequate food. It takes extensive research and trialing to create a diet like this, for one, and two, “regular” brands who cannot label their food as a “prescription” or “vet diet” may have a hard time marketing a food that is nutritionally incomplete.

Feline Natural used to show up on the list of best foods for cats with hyperthyroidism. It has a iodine content of 0.5. My cat love it. However, it is not on your list now. Why is that?

I prefer not to buy Hills as they use undigestible items as fillers in their ingredients. But Hills is the only company that makes food specifically for cats with Hyperthyroidism. They claim their food has 0.32 ppm of iodine. The percentage of older cats who get hyperthyroidism is high – I think 20% of the elderly cat population. Why don’t we have more choices?

Hello Megan, thanks for contacting us! I must have made a mistake, as 185 calories per cup seems to be accurate! Thank you for letting us know—I’m correcting the content now.

We stared feeding our three Ragdolls FN wet canned last November because we were having difficulties getting ZiwiPeak. Their stools virtually have no odor on FN, however all three started having VERY dry, crumbly stools and straining to eliminate. I know this isn’t healthy so we have reintroduced the ZiwiPeak mixing it with FN and their stools have returned to normal. (the odor has returned as well and I realize that this is probably because of the garbanzos ZiwiPeak adds. I was wondering if you’ve heard of anyone else has experiencing this.
(We always add extra water per can, appropriately 3 tablespoons but that didn’t make a difference in their stools with FN)

Hi Mallory,

Why is Feline Natural not good for cats with kidney problems? Are you referring to the freeze dried, canned, or both? The previous commenter sounded like his/her cat got kidney problems after consuming Feline Natural freeze dried for years. Also, some of their canned food, the calcium/ phosphorus ration is around 1.75:1 which seems a bit high on the calcium? Would that potentially cause kidney stones or problems in the long run? Thanks.
