[Written by a Veterinarian] What is Therapeutic Cat Food? Explaining How to Choose and Feed It

You may have been recommended a therapeutic diet for treatment at a veterinary clinic. Many pet owners often wonder, "How is a therapeutic diet different from regular cat food?" or "Is it really necessary for my cat?" In this article, a veterinarian explains the basics of therapeutic diets for cats and how to incorporate them effectively.

What is a therapeutic diet for cats? Let's start with the basics

Difference between therapeutic diets and complete and balanced diets

A complete and balanced diet is formulated to provide all the necessary nutrients for a cat, ensuring they can maintain their health with just that food and water. A similar type of product is called a general diet (or complementary food), which is not formulated for complete nutritional balance and is often used to enhance palatability. A therapeutic diet is a special food designed for treating diseases, and it must be prescribed by a veterinarian.

While complete and balanced diets are sold in pet shops and home centers, therapeutic diets require a veterinary prescription and are only available at limited locations such as veterinary clinics.

Common conditions requiring a therapeutic diet (Kidney disease, urinary stones, obesity, diabetes, etc.)

There are many types of therapeutic diets, ranging from those for diarrhea or vomiting to those for long-term use in conditions like kidney disease. Major diseases requiring a therapeutic diet include renal and urinary tract disorders like kidney disease and bladder stones, metabolic diseases such as diabetes, weight loss formulas, and diets for allergic conditions.

A therapeutic diet is not a drug, but a part of "dietary treatment"

Therapeutic diets are usually needed for diseases that require long-term or lifelong treatment. Depending on the disease, certain components in the food must be restricted. For example, protein must be restricted for kidney disease, and sugar must be limited for diabetes. Since these conditions cannot always be controlled by medication alone, dietary management serves as a necessary support for treatment.

Points to note when feeding a therapeutic diet to your cat

It is important to start based on a veterinary diagnosis

Therapeutic diets require a prescription from a veterinarian. While "prescription" often just means the vet suggests a specific diet during a consultation, the veterinarian is the one deciding which food is best for the treatment. Therefore, we generally ask owners not to purchase these diets based on their own judgment.

Additionally, veterinarians also provide instructions on the feeding amount. There have been cases where owners purchased therapeutic diets online and decided the portion sizes themselves, leading to weight issues or poor physical condition. If there is a therapeutic diet you are interested in, please consult your primary veterinarian.

Tips if your cat won't eat it (Transition methods, scent, and temperature)

Unlike complete and balanced diets, therapeutic diets have specific nutrient adjustments. Consequently, some cats may refuse to eat them. This is common with kidney diets in particular, as the protein—which provides the savory flavor cats love—is restricted.

When starting a therapeutic diet, transition over about two weeks. This helps the cat get used to the taste and helps them understand that the new food is indeed their meal. You may feel anxious about the need to switch and be tempted to do it quickly, but please take your time. Start by replacing 10% of their current food with the therapeutic diet. If they are reluctant to eat it, you can start with an even smaller amount. Increase the amount of the therapeutic diet by 10% each day, completing the transition in about two weeks.

Warming the food slightly can enhance its aroma and pique your cat's interest. Always check that the food is not too hot before serving. Using wet food or softening the kibble with a little water can also be effective.

Points to note in multi-cat households

In households with multiple cats, there is a risk that other cats might eat the therapeutic food, or the cat needing the diet might eat someone else's food instead. In some cases, the cat that needs the therapeutic diet may not be eating enough. When feeding a therapeutic diet in a multi-cat household, it is best to separate the cats during meal times. Do not leave food out; serve it only at set times and remove it when the cat is done. Remember to do the same with the other cats' food.

Frequently Asked Questions (FAQ) about therapeutic diets for cats

Do I need to continue the therapeutic diet for life?

It depends on the condition; some diets are temporary, while others must be continued for life. Since the duration is determined by your veterinarian, please do not discontinue it on your own.

Can I mix it with regular cat food?

You should feed the therapeutic diet alone. However, you may mix them briefly during the transition period. If you are unsure about how to feed, please consult your veterinarian.

Is it okay to purchase therapeutic diets online?

Therapeutic diets require a veterinarian's prescription. Many manufacturers restrict online sales, making them available only through authorized websites. Even then, you may need a referral from your clinic to purchase them. If your veterinarian approves of your online purchase, you may continue to do so. Buying online has the benefit of home delivery and scheduled shipping. However, if you decide to change the type of food, you must consult your veterinarian first.

What are the alternatives if my cat refuses to eat it?

If your cat absolutely refuses the food, you might try a different brand of therapeutic diet. Even within the same brand, there are often several flavor variations. First, try to find a formula that your cat will eat. Softening the food with water can also help. If they still refuse to eat, treatment may need to be managed through medication.

It is not recommended to give your cat anything other than the therapeutic diet based on your own judgment. Always consult your veterinarian.

Conclusion | Choosing a therapeutic diet suited to your cat's health

A therapeutic diet is a necessary part of treating diseases. It acts as a support for medical treatment, helping your cat live a healthy life.

These diets require a veterinarian's prescription. Please do not purchase or discontinue the food on your own; always consult your veterinarian.
