If your cat has suddenly started peeing on the rug or crying out in the litter box, you are probably worried. That instinct is spot on. Urinary tract infections (UTIs) are not just uncomfortable, they can become serious quickly. The good news is that catching the signs early makes a huge difference. In this guide, we will walk you through exactly what to look for, from subtle changes in behavior to obvious physical symptoms, so you can get your cat the help they need. Remember, while this information is a great starting point, always check with your veterinarian for a proper diagnosis and treatment plan.

Frequent Trips to the Litter Box (Pollakiuria)

One of the first and most noticeable signs of a UTI is that your cat seems to be visiting the litter box constantly. You might notice them hopping in, squatting for just a few seconds, and then hopping out, only to repeat the process ten minutes later. This is called pollakiuria, and it happens because the infection irritates the bladder lining, making your cat feel like they need to go even when the bladder is nearly empty. If your cat is also spending a lot of time scratching around the box or seems restless, pay attention. A stressed cat might also benefit from a calming environment; you can learn more with our guide on the best calming diffuser kits for every budget to help reduce anxiety during recovery.

Straining or Crying While Urinating (Dysuria)

Another major red flag is when your cat appears to be straining or seems in pain while trying to pee. You may hear them meow, yowl, or even hiss while in the litter box. This is called dysuria, and it can be caused by inflammation, bladder stones, or a blockage. If your cat is straining but producing little to no urine, this is a medical emergency, especially in male cats. Do not wait. A blocked urethra can be fatal within 24 to 48 hours. For cats that are prone to urinary issues, keeping them hydrated is key, and using a high-quality water source can help. Consider elevating their water bowl with something like the Necoichi elevated ceramic cat bowl to encourage better posture and more comfortable drinking.

Blood in the Urine (Hematuria)

Seeing blood in your cat’s urine can be alarming, and it is a clear sign that something is wrong. The urine might look pink, red, or even have visible clots. Hematuria often accompanies other UTI symptoms and indicates significant inflammation or damage to the urinary tract lining. While it is most commonly caused by a UTI or bladder stones, it can also signal more serious conditions like tumors or trauma. If you spot blood, collect a urine sample if you can (your vet will likely need one) and call your vet immediately. In the meantime, make sure your cat is comfortable and has easy access to a clean, quiet space.

Urinating Outside the Litter Box (Periuria)

When a cat that is normally well-trained starts peeing on beds, carpets, or laundry, it is easy to get frustrated. But before you blame bad behavior, know that this is often a medical cry for help. Cats associate the litter box with pain, so they start looking for other spots that feel safer or softer. This is called periuria. If your cat is suddenly having accidents, do not punish them. Instead, rule out a UTI first. Also, check if the litter box itself is clean and accessible. Sometimes, adding a second box or switching to a low-sided box can help a cat that is sore. A comfortable resting area can also reduce stress; check out our picks for the best cat scratching barrels and posts for happy cats to give them a positive outlet.

Excessive Licking of the Genital Area

Cats are naturally clean animals, but if you notice your cat obsessively licking their genital area, it is often a sign of irritation. The constant licking can be a response to the burning sensation or discomfort caused by a UTI. You might also see redness or swelling around the opening. While some licking is normal, if it becomes excessive and your cat is also showing other signs from this list, a UTI is very likely. Keep an eye on their overall behavior, as a cat in pain may also hide more or become less interactive.

Fun Fact: Cats and Water Intake

Did you know that cats evolved from desert animals and have a naturally low thirst drive? This makes them prone to concentrated urine, which can lead to crystals and UTIs. Feeding wet food or adding water to dry kibble can help increase their moisture intake. Some cats even prefer running water from a fountain. Keeping your cat well-hydrated is one of the best preventive measures you can take.

Changes in Appetite, Thirst, or Mood

A UTI does not just affect the bladder, it affects your cat’s whole body. You might notice they are drinking more water than usual (polydipsia) as their body tries to flush out the infection. Conversely, they might lose their appetite because they feel nauseous or in pain. Their mood may shift too: a normally friendly cat might become withdrawn, irritable, or even aggressive when touched near the belly. If your cat is also vomiting or seems lethargic, the infection may have moved to the kidneys, which is a serious condition called pyelonephritis. This requires immediate veterinary attention. To help manage your cat’s overall health, consider a diet that supports urinary health, and you can explore options like the best indoor hairball cat food reviewed for a balanced, moisture-rich diet.

Recognizing these signs early is the best way to prevent a minor UTI from becoming a major health crisis. If you see even one or two of these symptoms, especially straining or blood, call your vet. They will likely want a urine sample and may run tests to rule out crystals, stones, or blockages. With prompt treatment, most cats recover fully within a week. You can help by keeping their environment low-stress, ensuring fresh water is always available, and providing plenty of enrichment. A happy, healthy cat is worth every bit of attention.
