Flumax vs Kaminox: Cat Respiratory and Kidney Support Explained

Two supplements, two different jobs

Flumax and Kaminox are both cat supplements from Petplanet, but they are not interchangeable. Flumax is a respiratory support paste for cats with upper respiratory tract problems, while Kaminox is a liquid supplement for cats with reduced kidney function and low blood potassium. Choosing between them starts with identifying which health issue you are addressing—not comparing price or format alone.

This comparison breaks down what each product contains, how it is given, and what the supplied information does and does not tell you, so you can make a more informed decision with your vet.

Flumax: respiratory support in a palatable paste

• Flumax Respiratory Pump for Cats - 150ml: Flumax is a palatable paste for easy administration, supplied in a 150ml bottle. Paste format can be useful for cats that resist liquids, and the 150ml size gives you a sense of supply duration once your vet confirms a serving amount.

  

• Flumax Respiratory Pump for Cats - 150ml: Flumax contains a unique combination of amino acids, plant extracts, vitamins and minerals, and is formulated to help maintain respiratory tract health while decreasing shedding. These ingredients align with respiratory support and coat/shedding management, but the supplied information does not specify exact quantities or clinical claims.

Kaminox: kidney and potassium support in a liquid

• Kaminox Kidney Liquid Supplement for Cats - 120ml: Kaminox is a palatable liquid supplement intended for cats affected by reduced kidney function and associated with a reduced blood potassium level, supplied in a 120ml bottle. Liquid format can be given directly by mouth or added to food, which may suit cats with appetite challenges—but the 120ml bottle size is smaller than Flumax's 150ml.

  

• Kaminox Kidney Liquid Supplement for Cats - 120ml: Kaminox contains 234mg potassium per ml, with additional B-vitamins and essential amino acids for nutritional support, and is suitable for cats with chronic renal failure or other disorders associated with low blood potassium. The potassium concentration is a key difference from Flumax, which does not list potassium among its supplied ingredients. This makes Kaminox specifically relevant to kidney-related potassium loss.

Side-by-side: format, key ingredients, and bottle size

The table below summarizes the main supplied differences. Neither product includes preparation or operating instructions in the available evidence, so serving amounts and frequency must come from your veterinarian.

• Flumax Respiratory Pump for Cats - 150ml: Paste format; 150ml bottle; contains amino acids, plant extracts, vitamins and minerals; intended for respiratory tract health and shedding reduction.
• Kaminox Kidney Liquid Supplement for Cats - 120ml: Liquid format; 120ml bottle; contains 234mg potassium per ml plus B-vitamins and amino acids; intended for reduced kidney function with low blood potassium.

What the supplied information does not tell you

Neither product record includes feeding amounts, frequency, or safety warnings. That is a real limitation: you should not guess a dose based on bottle size or ingredient lists. Your vet needs to assess your cat's condition, weight, and bloodwork before either supplement is started, especially Kaminox because potassium levels can be dangerous if they are already normal or high.

Similarly, the records do not confirm compatibility with other medications or prescription diets. If your cat is on other treatments, ask your vet whether Flumax or Kaminox fits the overall plan.

How to choose between Flumax and Kaminox

Use these decision prompts to narrow the choice, then confirm with your vet.

• If your cat has upper respiratory signs such as ulcers or flu-like symptoms: Flumax is the relevant option in this catalog, as it is formulated for respiratory tract health. The paste format may be easier to administer than a liquid for some cats.
• If your cat has reduced kidney function and low blood potassium: Kaminox is the relevant option, as it supplies potassium and is intended for chronic renal failure or similar disorders. Its liquid format can be added to food or given directly.
• If you are unsure which condition your cat has: Do not choose based on price or bottle size. Respiratory and kidney issues require different diagnostics; ask your vet before starting either supplement.
