Cats with illnesses and chronic conditions often require prescription diets to manage their health needs. These diets are tailored to address specific issues, such as urinary tract health, weight management, allergies, and kidney support. For example, a cat with chronic kidney disease may require a diet with reduced protein content to aid in the excretion of protein waste products. While prescription diets are beneficial for cats with certain conditions, they should be administered under veterinary guidance and may not be suitable for healthy cats. These diets can be expensive and are typically prescribed as part of a treatment or management plan for cats with specific health concerns.

Urinary tract health
A prescription diet is often the best option for cats with ongoing serious urinary tract health issues. Prescription cat food can help prevent and heal lower urinary tract disease. It can also help to eliminate symptoms and signs of feline lower urinary tract disease (FLUTD) and create ideal pH levels in urine.
FLUTD symptoms include straining in the litter box, increased urination, blood in the urine, urinating in unusual spots, and excessively licking the genitals. If your cat is passing little or no urine, they may have a urethral obstruction, and you should contact your veterinarian right away.
Urinary diets are formulated to support the appropriate urinary pH and level of dissolved minerals within the urine. When pH and mineral levels in urine are out of balance, it can cause bladder stones, crystals, inflammation, or infection. Ingredients such as omega-3 fatty acids help curb inflammation in the urinary tract, while controlled levels of minerals like calcium, phosphorus, and magnesium can minimize the buildup that can result in the formation of calcium oxalate stones and struvite crystals.
Prescription diets can be expensive, but they are not the only option. Non-prescription alternatives include Purina Pro Plan Urinary Tract Health Canned Cat Food, Weruva Frisky Fishin’ Friends Canned Cat Food, and IAMS Proactive Health Adult Urinary Tract Health Dry Cat Food.

Weight management
Prescription weight management diets for cats can help activate their metabolism while keeping them feeling full and satisfied. These diets are carefully formulated to ensure cats get the proper nutrition they need while managing their weight. This can include restricted amounts of certain minerals, proteins, or carbohydrates, which may be unnecessary for healthy cats but are carefully limited for those with weight issues.
For example, a cat with chronic kidney disease (CKD) may require a prescription diet with less than half the amount of protein normally present in cat food. This is because cats with CKD have difficulty excreting protein waste products from their kidneys. Prescription diets can also help maintain a lower pH level in the urine, preventing bladder stones and other urinary issues.
It is important to note that prescription weight management diets for cats should only be fed under the guidance of a veterinarian. While these diets are safe and can be beneficial for cats with weight issues, they are not suitable for healthy cats and can lead to nutritional imbalances if fed long-term without veterinary supervision.
Additionally, prescription diets can be more expensive than regular cat food due to the extensive testing they undergo. It is important to discuss any concerns about affordability with your veterinarian, as there may be other options available to help manage your cat's weight.

Kidney support
Prescription diets are an important tool for managing cats' medical needs, especially for cats with illnesses and chronic conditions. They are formulated to provide tailored nutrition to support the health of cats with specific diseases. For cats with chronic kidney disease (CKD), prescription diets are designed to reduce the workload on their kidneys.
Medicus Kidney Support Diet is another option that requires signed authorization from a veterinarian. This diet is designed to provide the necessary nutrients for cats with CKD while lessening the kidneys' workload. It includes moderate levels of protein from meat and organs, and the addition of rice helps to reduce the high phosphorus content of the meat, which is crucial for protecting kidney function.
The Pet Wellbeing Kidney Support supplement is a liquid option that can be added to your cat's food. It is important to note that these diets and supplements should only be introduced under the guidance of a veterinarian, as they are specifically formulated for cats with CKD and may not be suitable for healthy cats.
Some cat owners have reported success in managing their cat's kidney health with prescription diets. One cat owner shared that their cat was on a prescription urinary health diet for eight years and never had crystals or a UTI during that time. However, it is important to consult with a veterinarian to determine the best course of action for your cat's individual needs.

Allergies
Cats can develop allergies to ingredients they have consumed for a long time, but they cannot develop an allergy to a food they have never been exposed to. The most common symptom associated with food allergies in cats is itching that is not seasonal and always present. Itching can occur anywhere on the body, but the head and neck are often involved. Less common symptoms include gastrointestinal issues such as vomiting and diarrhoea.
If your cat is exhibiting signs of food allergies, such as excessive scratching, skin irritations, vomiting, or diarrhoea, consult your veterinarian. They may recommend an elimination diet or hypoallergenic food to identify and manage the allergies. Prescription diets for cats with allergies typically avoid common allergens like beef, dairy, wheat, and soy, using novel or hydrolyzed proteins instead. This helps alleviate symptoms such as itching, vomiting, and digestive issues.
Hydrolyzed protein cat foods are routinely used to treat food allergies in cats. The proteins in these diets are broken down so that the cat's immune system cannot react to them. Most known food allergies are due to an abnormal reaction to intact proteins in food. Hydrolyzed protein diets are also often prescribed for cats with chronic digestive diseases, like inflammatory bowel disease (IBD). Cats with IBD are believed to have an inappropriate immune response to food substances, which results in symptoms.
Veterinary prescription is required for hydrolyzed protein diets, and they are to be used under the guidance of the veterinarian writing the prescription. There are strict quality-control guidelines to ensure that all proteins in these diets are broken down appropriately. These guidelines also ensure that hydrolyzed protein foods do not contain contaminant proteins. If a diet contains contaminant proteins, the cat’s symptoms may not improve.
In addition to prescription diets, there are other allergy medicines safe for cats, including antihistamines such as diphenhydramine (commonly known as Benadryl), chlorpheniramine, or cetirizine, and corticosteroids, when administered under veterinary supervision and in appropriate doses depending on the severity of symptoms. While these medications can effectively alleviate allergy symptoms in the short term, potential side effects may include drowsiness, increased thirst and urination, gastrointestinal upset, and in the case of corticosteroids, long-term use may lead to immunosuppression or exacerbation of certain conditions like diabetes or hyperthyroidism. It is crucial to follow your veterinarian's guidance closely and monitor your cat for any adverse reactions while using allergy medication.

Chronic conditions
Prescription diets are an important tool for managing cats' medical needs, especially for those with illnesses and chronic conditions. They are formulated to provide tailored nutrition to cats with specific health issues and should be fed only under the guidance of a veterinarian.
Chronic kidney disease (CKD) is a common condition in older cats, affecting an estimated 30% to 40% of cats over 10 years old and more than 10% of cats over 15 years old. Diet modification is a proven aspect of CKD treatment, as cats with this condition have difficulty excreting protein waste products from their kidneys. Prescription diets for CKD typically contain significantly reduced levels of protein.
Urinary care prescription diets are another common type of prescription diet for cats. These diets help to maintain a lower pH level in the urine, making it too acidic for the formation of bladder stones or crystals. This type of prescription diet is particularly important for heavier cats, who are more prone to urinary issues.
Prescription diets for cats with allergies or intestinal problems may also be recommended. These diets typically feature alternative protein sources or more easily digestible ingredients. While these diets are safe for healthy cats, they are generally more expensive and unnecessary unless a health issue is present.
It is important to note that prescription diets for cats should not be used as a preventative measure. They are intended to treat or manage specific health conditions and may not provide complete and balanced nutrition for a healthy cat. As such, prescription diets should only be fed with veterinary authorization and ongoing oversight.
