Cat Hyperthyroid Diet Tracker

An iodine-limited diet for a hyperthyroid cat only works if it's the only thing they eat - no treats, no other food, no stealing from the dog's bowl. PetHealthLog lets you log the prescription food, keep the diet strictly exclusive, and track weight and appetite on one timeline. Free, no account, works offline.

An iodine-limited diet works only if it's exclusive

One way vets manage hyperthyroidism in cats is a special iodine-limited prescription diet. Its defining catch is that it has to be the cat's only food: a few treats, a taste of another cat's dinner, or table scraps can undermine the whole approach.

In a multi-pet home that's genuinely hard. Keeping a single cat on an exclusive diet, remembering it across the family, and noticing the slip-ups means an accurate record is the difference between a diet that's working and one that only looks like it is.

PetHealthLog is free, needs no account and works offline, so logging the prescription meals - and noting any slip - keeps the diet honest and gives your vet a clear record for the next thyroid test.

What the tracker actually does

Common hyperthyroid-cat everyday supplies (#ad)

The iodine-limited prescription diet itself must come from your vet, and on this diet other foods and treats are usually off-limits. These are common everyday feeding supplies - check with your vet before adding anything your cat eats.

Frequently asked questions

Is this cat hyperthyroid diet tracker really free?
Yes. Logging the prescription diet, noting slips, tracking weight and appetite, recording blood-test dates, and the PDF report are all free. There is no sign-up and no account, and your cat's records stay on your own device.
Why does the diet have to be exclusive?
An iodine-limited diet relies on the cat eating it and nothing else, so treats or other food can work against it. The tracker helps you log meals and note any slip-ups so you and your vet can see how strictly the diet was kept; your vet decides how to manage it.
How is this different from a hyperthyroid medication tracker?
This page is for cats managed with a special diet rather than daily medication. If your cat is on anti-thyroid medication instead, a medication schedule tracker fits better - and PetHealthLog handles both.
Does it work offline?
Yes. PetHealthLog is a progressive web app that works offline, so you can log a meal or a weigh-in without a connection.
Is this a substitute for veterinary advice?
No. PetHealthLog is a record-keeping tool, not veterinary advice. Hyperthyroidism must be diagnosed and the treatment chosen by a licensed veterinarian; the tracker just records what your cat ate and how they did.
