    Causes of Kidney Disease in Cats

    Kidney disease in cats is a serious condition in which the kidneys become damaged and unable to filter toxins out of the blood. It can be caused by a number of factors, including age-related decline, chronic infections, dehydration, toxins, and certain medications. Kidney disease can also be genetic or be caused by a structural abnormality.

    Symptoms of kidney disease include:

    • Increased drinking and urinating (polydipsia and polyuria)
    • Weight loss
    • Decreased appetite
    • Bad breath (halitosis)
    • Vomiting
    • Lethargy

    A veterinary examination will help to diagnose kidney disease in cats so that appropriate treatment can begin. Treatment for cats with kidney disease involves providing supportive care such as fluid therapy, dietary support, medications to control symptoms such as nausea or pain, and possibly specialty diets that are low in phosphorus or other elements.

    Symptoms of Kidney Disease

    Kidney disease is a common condition in cats that can be caused by many different factors including infections, chronic dehydration, congenital disorders, and dietary imbalances. It is important to know the symptoms of kidney disease in cats so that you can get your pet the help they need right away.

    Common symptoms include:

    • Drinking and urinating more than normal
    • Lethargy
    • Poor appetite or refusing to eat at all
    • Weight loss despite an increase in appetite
    • Vomiting or diarrhea
    • Bad breath from increased toxins in the blood (uremia)
    • Dehydration

    If any of these symptoms present themselves in your cat it is important that you take them immediately to the veterinarian for diagnosis and treatment. Early diagnosis and treatment is key to helping your cat maintain a good quality of life even if they are suffering from kidney disease.

    Dietary Considerations

    Cats with kidney disease require a special diet to ensure their nutritional needs are met and their condition is managed properly. By making sure that their diet is tailored to meet their specific dietary needs, you can help to improve their quality of life and keep them healthy.

    Let’s explore some of the dietary considerations when feeding a cat with kidney disease:

    Reduce Protein Intake

    Reducing the protein intake of cats with kidney disease is a crucial dietary consideration. This is because when cats are struggling with kidney disease, there is increased nitrogen waste in the bloodstream, which can further tax the kidneys. Protein helps to break down into nitrogen waste and by reducing it in their diets, there is a much lower level of nitrogen waste.

    It’s important to note that this does not mean eliminating all proteins from their diet – cats still need some level of protein for their general wellbeing and to help regulate their body functions. Instead, the goal should be to ensure that the proteins provided are easily digestible (such as fish-based proteins) and low in phosphorus content.

    For cats with moderate or advanced kidney disease, it can be helpful to talk to a veterinary nutritionist or consultant who can give tailored advice on how best to adjust protein levels for your cat’s specific condition and needs.

    Increase Water Intake

    Cats with kidney disease must have their water intake increased to flush out toxins from the body. This is best achieved by providing multiple sources of water, such as water bowls in various locations of the house and wet cat food.

    In addition to this, adding additional liquid sources to your cat’s diet, like low-sodium chicken broth or canned tuna juice, will also help increase the cat’s overall water intake. As cats do not naturally drink large amounts of water like humans do, it is important to make sure there are multiple sources of fresh drinking water available at all times in order to ensure they are getting an adequate amount. Providing separate drinking bowls such as fountains may also encourage your cat to drink more often and can be beneficial for cats with chronic kidney disease.

    Increase Fiber Intake

    Increasing the fiber in a cat’s diet is an important step for cats with kidney disease. Fibre helps to slow down digestion, which can reduce the load on the kidneys. It also helps to add bulk and reduce hunger, which helps cats regulate their food intake and control weight more easily.

    Fibre can be added to a cat’s diet in several ways, including:

    • adding canned pumpkin
    • psyllium husk powder
    • just adding high-fiber dry or canned food

    When adding fiber sources to your cat’s diet, it is important to introduce them gradually over the course of several days or weeks. Make sure to monitor your cat’s stool regularly, as too much fiber can lead to constipation and other issues. Increasing fiber intake is an important step for helping cats with kidney disease maintain a healthy lifestyle.

    Increase Vitamin B Intake

    Cats with chronic kidney disease (CKD) can benefit from a diet high in Vitamin B which helps to support the body’s functioning. Increasing their Vitamin B intake can have positive effects such as restoring energy, decreasing pain, and improving appetite. A diet rich in Vitamin B6 and B12 can be achieved with seafood, poultry, red meat potatoes, eggs, milk and dairy products such as cheese and yogurt.

    It is important to note that when making dietary changes for your cat it is important to speak with your veterinarian first.

    A simple way to increase your cat’s vitamin B intake is by adding supplements specifically designed for cats with CKD or supplements packed with other essential vitamins like Omega 3 fatty acids or probiotics. Additionally it is important to read labels carefully as not all supplements are safe for cats. Additionally it is important to understand any potential side effects of supplementation before giving them to your cat.

    Food Choices

    When it comes to the best diet for cats with kidney disease, there are many different factors to consider. Not only do cats with kidney issues require a diet low in phosphorus, but they also need to get enough protein, vitamins, minerals, and water. Choosing the right food for your cat can be a tricky process, but there are certain food options that may help them with their specific needs.

    Let’s explore some of the best food choices for cats with kidney disease:

    Canned Food

    For cats with kidney disease, canned food is the best choice. This type of food contains high levels of water and essential nutrients. Canned food also has more calories than dry type food, which helps cats who have a hard time eating due to decreased appetite.

    When looking for canned food for your cat it is important to find one that does not contain an excess of phosphorus and sodium as these compounds can cause further harm to your cat’s kidneys.

    Another great choice is wet pate style foods that are low in phosphorus and sodium; these types of foods are ideal for cats with kidney disease as they are easy to eat and digest, and they provide the optimal nutrition needed while avoiding excess phosphorus or sodium. Additionally, most brands offer added vitamins, minerals and other beneficial supplements that can help maintain kidney health in cats with chronic renal failure or other forms of feline renal diseases.

    Dry Food

    Dry food is one of the best diet options for cats with chronic kidney disease (CKD). Dry kibble is a good source of protein and low in phosphorus, making it an ideal choice for cats with CKD. This type of food will also help to keep your cat’s mouth clean and healthy. The crunchy texture helps to remove plaque and tartar buildup, while the moisture content helps to keep your cat hydrated. Additionally, dry kibble can help provide necessary vitamins and minerals that may not be available in wet foods.

    Be sure to consult with your pet’s veterinarian before making dietary changes as everyone’s pet needs are unique. When choosing dry food, look for high-quality options that are low in phosphorous, sodium, and other minerals like calcium.

    Homemade Food

    For cats with chronic kidney disease, feeding a homemade diet can provide a variety of health benefits. These include:

    • A balanced, nutrient-dense diet customized to fit your cat’s individual needs
    • High moisture content and fewer preservatives than canned food
    • Prevention of metabolic imbalances due to inadequate nutrition from commercial diets

    When making a homemade diet for cats with kidney disease, it is important to use ingredients that are easily digestible and low in phosphorus. You should also provide adequate protein for your cat’s body functions as well as essential fatty acids for skin and coat health. Additionally, the diet should contain antioxidants such as vitamin E, selenium, and long-chain omega-3 fatty acids which may slow the progression of kidney disease.


    When it comes to choosing the best diet for cats with kidney disease, there is no one-size-fits-all answer. Every pet and individual situation is different. Speak to your vet about what type of food would best suit your cat.

    In addition, you should look for a diet that has lower phosphorus levels, tailored towards a cat’s specific kidney condition and contains high quality proteins and other essential nutrients for better overall health. You can also prepare food at home specifically for your cat that takes into account their particular dietary needs and restrictions.

    Ultimately, the goal should be to provide our cats with the best possible nutrition to help improve their overall health.
