Felines are obligate carnivores, consuming animal-based proteins for the bulk of their diet. That’s significant because it plays a direct role in our list of facts about cat pee below. Some scientists view cats as the ultimate example of evolution because of how well-adapted they are to their niche in the food chain, and you better believe their urinary system plays a supporting role.

The 6 Facts About Cat Pee

1. Urine Production Serves Several Functions

To confine the urinary system only to waste removal negates the other vital functions it serves for felines, humans, and other mammals. It also plays a crucial role in blood pressure by influencing blood volume and sodium retention. The body strives to maintain a balance between the concentration of ions within the inter- and intracellular environments.

The urinary system influences blood cell production indirectly through the kidney’s secretion of erythropoietin, a hormone that stimulates hematopoiesis in the bone marrow. It maintains the electrolyte balance, which controls many critical functions. Basically, cat urine is imperative to the animal’s existence.

2. Scent Marking Is an Essential Component of Feline Non-Vocal Communication

Felines live in an olfactory world. Humans have only 2.5% of the scent receptors that our cats have.¹ Cats possess an estimated 45–80 million scent receptors, compared to about 5 million in humans. The sense of smell comes into play in many areas for cats, where it doesn’t with humans. One way is through scent marking. Felines use this to delineate their territories. This non-vocal communication helps these animals avoid conflict.

Fights between cats are costly, whether you’re the victor or the loser. It makes evolutionary sense to avoid this gamble. Scent marking accomplishes this goal. Cats deposit scent not only through urine but also through glands on their face, paws, and tail base. Urine marking is one of several forms of olfactory communication.

3. Cats Don’t Urinate as Frequently as Dogs

Cats don’t urinate frequently compared to dogs (two to four times per day compared to a dog’s three to five times). However, it’s often concentrated when they do. Cats naturally have highly concentrated urine, which is an adaptation for water conservation, but this can predispose them to urinary issues if fluid intake is insufficient. On average, they require about 50 milliliters of water per kilogram of body weight per day (approximately 4 ounces per 5 pounds), including the moisture contained in their food.

4. There Are Different Kinds of Peeing

If your cat is peeing outside the litter box, there is a chance that they are spraying instead of urinating. What’s the difference? Spraying or marking is often done on vertical surfaces and lets other cats know that something is theirs, whether it’s a toy or territory.

However, some cats also pee outside the litter box when they are ill, stressed, or experiencing pain. This type of urination is usually a sign of distress and appears on horizontal surfaces. Inappropriate urination can also indicate medical issues such as feline lower urinary tract disease (FLUTD), idiopathic cystitis, urinary tract infections, or bladder stones, so a veterinary exam is essential before assuming it is behavioral.

5. Frequent or Painful Urination Is a Sign of Health Issues

Domestic cats fed a commercial diet with enough water usually urinate about twice daily. That makes it easy to determine when something is amiss. Felines often hide pain and illnesses, making it challenging to identify them in the early and detectable stages. However, it’s hard for them to keep it under wraps if you notice frequent or painful urination. This is often a sign of urinary tract inflammation, infection, or crystals/stones.

It’s essential to act quickly. Remember that the condition has been ongoing before these behavioral signs are evident. That’s good advice for anything unusual you observe with your cat. They are masters at hiding their weaknesses, after all. In male cats, urinary obstruction from crystals or stones is a medical emergency requiring immediate veterinary attention.

6. A Urinalysis Can Offer a Lot of Info About Your Kitty

Your vet may order a urinalysis as part of your cat’s annual exam, especially if they have a medical history of issues. This test yields much information, even if it’s not the most comfortable procedure for your pet to endure. When combined with bloodwork, it provides valuable insight into your kitty’s kidney function and metabolic health.

Tips for Your Cat’s Urinary System Health

To keep your cat healthy, we recommend filling your cat’s bowl with fresh, cold water daily. Remember that felines are scent-aware, so make sure you rinse it well after cleaning it. Of course, the amount your kitty drinks depends partly on the type of food you give your pet. However, other factors can affect their consumption.

For example, a diabetic cat may drink more than a healthy animal. Likewise, a pet experiencing vomiting or GI distress will need more water to make up for what they’re losing. Other signs of dehydration include the following:

You should contact your vet if you notice any of these signs. They can indicate an underlying condition that requires treatment. Encouraging water intake through multiple bowls, cat fountains, and wet food can significantly reduce urinary tract issues.

Conclusion

Your cat’s urinary system is vital for ensuring fluid and electrolyte balance in their body. Felines differ from many other animals because of their meat-based diet. Proper hydration is necessary so that this system can do its job efficiently. While cats often hide signs of illness, their urine and its production can often reveal when something is wrong. Careful observation of habits and subtle changes, as well as regular veterinary exams and urinalysis, are among the best ways to detect early kidney or urinary tract disease.
