Pros and cons of using iodine-free cat food recipes

The main advantage of cooking your homemade cat food is knowing exactly what goes into the meals.  You can include other vitamins and minerals if needed, plus you can adjust the recipes according to your kitty’s needs.  

Homemade and Healthy Cat Food Recipe | Vet Approved

Fish and seafood are excellent sources of iodine, so it may be necessary to use them as ingredients for your cat’s meals if any sensitivities or allergies are present.  If you prefer not to use seafood, it is best to get iodine from other sources such as vegetables.

Iodine free homemade cat food does not have the usual strong fish odor, so you may want to consider making your kitty’s meal instead of buying commercially canned food.

Cooked recipes are also more expensive than commercial food, but it is up to you and your budget whether this will be a problem.

Homemade cat food can be stored for 3 days in the fridge or frozen for later use.  Just make sure all meals are labeled correctly with ingredients and the cooking date before storing them away.

Tips for feeding an iodine-free diet to your kitty

If you are concerned about your cat’s diet, check the ingredients of any commercial food.  Cats may need iodine in their diet if they suffer from hairballs, bald patches, or frequent urination.

Commercial foods often contain larger amounts of iodine than homemade meals, so consider switching to homemade if needed. The same goes for cats that are pregnant or nursing.

Cats need at least 150mcg of iodine per day, but this may be higher depending on the cat’s size, age, and activity level.  If you are feeding your kitty a homemade diet, it is best to ask your vet how much iodine should be included.

Always wash your hands after handling raw meat and before touching or preparing a meal for your kitty.

Avoid using iodine products when washing dishes after cooking since the iodine may affect the palatability of your cat’s food.  Iodine can be removed from surfaces by wiping with lemon juice then rinsing with water.

How To Find Iodine Free Cat Food?

If your cat has a specific medical condition, ask your vet for advice before switching to iodine-free food.

Purchasing commercially canned food is the easiest way to ensure you are only giving your kitty iodine-free meals.  There are many brands on the market, so choose one your cat enjoys and check their website or packaging for information on iodine content.

Organic cat food is another option that can help you avoid iodine since organic plants are grown in soil free from synthetic fertilizers and pesticides.  Since most commercial plants are grown in nutrient-enhanced soil, switching to organic for your kitty may reduce the need for using iodine-free food.

What Does Cat Food Not Have Iodine In It?

The following foods do not have added iodine:

  • Organic cat food
  • Whole grains such as brown rice and millet
  • Seafood from the seaboard
  • Cottage cheese and quark

Many websites provide a list of ingredients to avoid using when making your kitty’s meals.  Reading a label or two should help you understand if any ingredients cannot be used.

Blue Wilderness Cat Food contains a small amount of iodine since it contains fish meal from the Pacific Ocean.  This is only around 2 mcg of iodine per 100 grams of food, which is less than half found in most commercial cat foods available today.
