Top 9 Best Non-Prescription Cat Food for Urinary Crystals

How to choose the Best Non-Prescription Cat Food for Urinary Crystals? Feline Lower Urinary Tract Disease (FLUTD) is one of the most diagnosed conditions in pets. FLUTD refers to a group of urinary problems rather than a specific issue, but many forms of FLUTD are caused by urinary crystals that block the urethra.

Cats with urinary crystals struggle to urinate; you’ll probably notice your cat keeps going to the litter box, but nothing happens! Or on the other hand, maybe your cat keeps trying to pee, but only a little comes out. Such issues cause unwanted behaviors too, such as your cat urinating outside the litter box. Besides, the presence of these urinary crystals causes severe pain and discomfort for your furry friend.

Your best option for treating these conditions is to speak to your vet, who will often prescribe special diets to reduce crystal formation. Unfortunately, these diets are notoriously expensive! But here is the good news: there are non-prescription urinary cat food alternatives that can be almost basically as effective as their veterinary-recommended counterparts.

In this article, I run through nine of the best non-prescription cat food for urinary crystals. I explain what makes these foods great for cats with urinary problems and how to choose the right food for your kitty. Remember, however; it is as yet advisable to speak to your vet before making a change. You don’t want to make your cat’s urinary issues any worse!

Best Non-Prescription Cat Food for Urinary Crystals

Before I run through every one of the top products, I want to emphasize what I’m referring to when I say non-prescription urinary cat food. Unlike prescription diets, these cat foods don’t contain any medication or drugs known to treat FLUTD. However, they have certain ingredients that discourage the formation of urinary crystals.

Below are key factors that the very best non-prescription cat foods for urinary crystals must have. Only those that scored well in each category made it onto this list of recommendations:

  • High Moisture Content: Cat food for good urinary health should ideally have a high moisture content. This helps to improve hydration and supports the production of less concentrated urine. And the more diluted the urine, the less likely crystals will form. Cats can obtain this through drinking, but as notoriously bad drinkers, high-moisture food helps.
  • Low Magnesium Content: Magnesium is found in most commercial cat foods and carries several health benefits in moderation. However, uric crystals form when such a lot of magnesium is consumed that it starts crystalizing in the urethra. Ensuring whatever you feed your cat has a low magnesium content keeps crystal formation to a minimum.
  • Low Ash Content: Ash in cat food refers to the inorganic mineral content left over when the organic content is burned off, normally a combination of magnesium, calcium, phosphorus, and more. Magnesium is the main mineral responsible for crystalizing in the urethra, but other minerals can likewise be detrimental. Therefore, it is worthwhile looking for low-ash cat food.
  • Low High-Quality Protein Content: After digestion, protein waste products are processed through the kidneys. High-quality protein is easier for the body to digest, putting less strain on the kidneys. Likewise, high-protein diets put more pressure on these vital organs. As the kidneys play a crucial role in urine formation, keeping them healthy is essential!

Now you know what the best cat food for urinary health without a vet prescription looks like. Anyway, are you ready to learn more about the top products on the market? Here are my top 9 recommendations for all cats with urinary crystals that can benefit from eating.

Non-Prescription Cat Food for Urinary Crystals: Buying Guide

Top 9 Best Non Prescription Cat Food for Urinary Crystals.
Best Non-Prescription Cat Food for Urinary Crystals

I’ve just given you the 9 best non-prescription cat food for urinary crystals. However, you must in any case choose the right option for your cat! As usual, I suggest getting a veterinary opinion before swapping cat food, but the factors below can help you narrow down your choices more easily.

Price and Budget

Anyone looking for non-prescription urinary cat food is likely to close on budget. After all, medicated diets from a vet are more effective in treating urinary issues than non-medicated versions; in the event that you can afford them, there is no need to not decide on a prescription diet. But as you’re trying to avoid prescription diets, affordability is probably a top concern.

Thankfully, you can find non-prescription alternatives that are budget-friendly. Nevertheless, I suggest going for the most expensive option you can afford. There is no price on your cat’s health, and the money you save on food may be spent on costly veterinary bills further down the line.

Quality of Ingredients

The price of cat food and the quality of the ingredients used generally remain inseparable; the better the quality of the ingredients, the more the food will cost. This is the reason opting for a more expensive product is beneficial. You are paying for better quality, and your cat’s body will thank you for it.

Continuously check the quality before purchasing any non-prescription cat food. You want to find products that contain real animal meat (rather than meat results), a low carbohydrate content (choosing wholemeal carbs where possible), and soy protein.

These low-quality ingredients can contribute to obesity, diabetes, kidney disease, and other medical issues. You’re searching for a new diet to improve your cat’s health rather than worsen it! Check the ingredients of all cat foods and ensure you choose a nutritionally balanced option, providing everything your cat needs without additional unhealthy fillers or empty calories.

Cat’s Preferences

Your cat’s preferences are crucial when deciding on its diet. In the event that you don’t find food, your cat enjoys the taste of, it could refuse to eat any food. This leads to malnourishment and several related health problems. Besides, your cat eating food it hates daily will make your unfortunate feline miserable. Imagine only ever eating food you hate until the end of your life – no, thank you!

Therefore, it is vital to find food your cat finds delectable. All cats have different preferences when it comes to food, so you need to consider what precisely your cat likes. You could know this already! And on the off chance that not, consider the food they eat currently. In the event that you can find a comparative cat food made specifically for urinary health, then this is a pretty safe option.

The two primary considerations are flavor and texture:

  • Texture: In the event that your cat prefers wet food, search for a urinary wet cat food non-prescription substitute. On the other hand, dry cat food for urinary health is better for cats that like kibble. In the event that opting for dry food, have a go at getting soft dry cat food with higher moisture content.
  • Flavor: Many different animal proteins are used to make cat food. Poultry is an excellent option as most cats love the taste. However, your cat could prefer salmon, tuna, beef, pork, liver, duck, or other animal protein sources!

Other Health Considerations

The best non-prescription cat food for urinary crystals works at actively preventing urinary issues from arising. However, while on the hunt for good urinary health, you cannot forget your cat’s other health needs. The food must support general good health, and some foods probably won’t be suitable for specific medical conditions.

Take anemic cats, for instance. They need iron-rich cat food that contains plenty of high-quality lean meat. Including extra iron in the diet increases the oxygen-carrying limit of the blood, helping to battle the side effects of anemia. Assuming your cat is anemic, you cannot substitute this high iron content for urinary-improving ingredients – the new food needs to help the two conditions.

Allergies are another health problem, so consider the food intolerances your cat has. You should search for wet cat food for sensitive stomachs to help ease digestion. Wet food is additionally beneficial for cats with painful dental conditions. Likewise, cats with kidney disease need food with low salt, phosphorus, and protein.

FAQs – Best Non-Prescription Cat Food for Urinary Crystals

Why do some cat foods require a prescription and others don’t?

Prescription foods are medicated diets with the right combination of nutrients and drugs to improve certain medical conditions.

Can cheap cat food cause urinary problems?

Yes, sometimes! Cheap cat food that uses low-quality ingredients often contains a high percentage of crude ash, meaning loads of magnesium, phosphorus, and calcium. These minerals can form deposits in the urethra and crystalize, causing urinary stones and blocked bladders. Yet not all expensive cat food uses quality ingredients – ingredient quality is definitely more basic than the price.

How might I tell how much magnesium is in cat food?

This depends on the brand! Some packaging clearly lists the content of magnesium, whereas brands list a percentage of ash rather than the breakdown of the individual minerals. This is as yet a good indicator of magnesium content. Non-prescription urinary cat food should ideally contain a maximum of 0.12% magnesium and up to 2.6% ash on a dry matter premise.

Final Thoughts – Best Non-Prescription Cat Food for Urinary Crystals

And there we have it – 9 of the best non-prescription cat food for urinary crystals. These all contain low magnesium, acidify urinary pH, and include good-quality protein that puts less strain on the kidneys.

They help to reduce the formation of crystals in the urethra, but they cannot remove blockages that are already there. In other words, they are preventative and best for cats with frequent urinary flare-ups instead of those diagnosed with FLUTD.

Therefore, speak to your vet in the event that you do think your cat has a real urinary issue. There are different side effects to pay special attention to – you could notice your cat is eating and drinking but not peeing. I generally have to stop my cat from peeing on my clothes of mine when she has a flare-up, as well.

Once diagnosed, your vet will actually want to prescribe medication to treat the condition. They could likewise suggest changing to non-prescription urinary cat food to help prevent future issues. Assuming you decide to change your cat’s diet regardless, consistently make the change gradually. This minimizes stress, improves your cat’s tolerance for the new food, and makes the transition ten times easier.
