If your cat is peeing just a little bit, or visiting the litter box often and producing only drops, the most likely causes are inflammation of the bladder (cystitis), urinary stones, infection, or a urethral blockage. A blockage is a medical emergency that can become fatal within a day or two, especially in male cats. Any cat who strains and produces little or no urine needs to be seen right away.

Quick Answer

Small, frequent urination is called pollakiuria. It means the bladder is irritated or the urine cannot flow out normally [1].
A male cat who strains, cries, or produces no urine may have a urethral obstruction. This is an emergency, go to a vet now.
Straining in the litter box can look like constipation. If you are not sure which one it is, treat it as urinary until proven otherwise.
Do not wait a day or two to "see if it passes." Cats with blockages can decline and die quickly.
Collect a fresh urine sample in a clean, empty container if you can, but never delay emergency care to get one.

What "Peeing Just a Little Bit" Actually Looks Like

Owners often describe this sign in different ways. Your cat may squat for a long time and pass only a few drops. She may hop in and out of the box every few minutes. You may find small wet spots on the carpet, the couch, or your bed. Some cats urinate outside the box entirely, which owners sometimes mistake for behavior problems. If your cat has started going outside the box, see Why Is My Cat Peeing Outside the Litter Box? for the full picture.

Normal urination in a healthy cat varies with diet, water intake, and body size. Most cats urinate two to four times a day, and the clumps in the litter box are usually a decent size. What matters most is the change. A cat who used to produce large clumps and now produces tiny ones, or who visits the box far more often, is telling you something is wrong.

Veterinarians group these signs under the term lower urinary tract signs. They include difficult or painful urination (dysuria), blood in the urine (hematuria), urinating outside the box (periuria), frequent urination (pollakiuria), and straining (stranguria) [1]. These signs look similar no matter what the underlying cause is, which is why testing matters [1].

Main Causes of a Cat Peeing Just a Little Bit

Cause	Typical clues	How urgent
Urethral obstruction	Male cat, straining with no urine, crying, hiding, vomiting, lethargy	Emergency now
Feline idiopathic cystitis (FIC)	Young to middle-aged cat, stress or change at home, small frequent clumps, sometimes blood	Same day
Urinary stones (urolithiasis)	Straining, blood, sometimes no urine if a stone blocks the urethra	Same day to emergency
Urinary tract infection	Frequent small urination, blood, sometimes foul odor, more common in older cats	Same day
Bladder parasites	Straining, urinating outside the box, lethargy, rare in cats	Routine to same day
Bladder foreign body	Long-standing straining and blood, often found on imaging	Same day
Kidney or ureter injury	Sudden severe signs after obstruction or infection, bloody urine, collapse	Emergency now

Urethral Obstruction

This is the cause that kills cats. A plug, stone, or spasm blocks the urethra, and urine backs up. The bladder stretches, pressure rises, and toxins build up in the blood. Male cats are at higher risk because their urethra is long and narrow. A cat with a complete blockage may cry out, pace, hide, vomit, or become very quiet. Some cats collapse. If your cat is producing no urine at all, or only a few drops with intense straining, go to an emergency clinic immediately.

Feline Idiopathic Cystitis

FIC is the most common cause of lower urinary tract signs in cats [1]. The bladder wall becomes inflamed without an obvious infection or stone. Stress plays a role, and the condition involves complex interactions between the bladder, the nervous system, the adrenal glands, and the cat's environment [2]. Cats with FIC often have episodes that come and go. They may pee small amounts in many places, including on your bed or clothes.

Urinary Stones

Stones form in the bladder or kidneys from minerals in urine. They irritate the bladder wall and can block the urethra, especially in male cats. After FIC, urolithiasis is the second most common cause of feline lower urinary tract disease [2]. Signs often mimic FIC, so imaging and urine testing are needed to tell them apart [2].

Urinary Tract Infection

Bacterial infections are less common in young cats than in older cats, but they do happen. Signs include frequent small urination, blood, and sometimes straining. A urinalysis and urine culture confirm the diagnosis. Your veterinarian will choose an antibiotic based on the results.

Less Common Causes

Bladder parasites are rare in cats. One report described a young cat with difficult urination, straining, urinating outside the box, and lethargy. Urine testing found Capillaria plica eggs, and the cat recovered after treatment [3]. Foreign bodies in the bladder are also rare. Two cats with long-standing straining and blood were found to have lead pellets in the bladder, which were removed with endoscope-assisted surgery [4]. Kidney and ureter injuries are uncommon but serious. One young cat developed a urethral obstruction, then later leaked urine from both kidneys, a condition that carried a poor prognosis [5].

Red Flags That Mean Emergency Now

Go to a veterinary emergency hospital immediately if you see any of these:

Your cat is straining in the litter box and passing no urine, or only a drop or two.
Your cat is crying, howling, or pacing and cannot settle.
Your cat's belly feels firm or painful when you touch it gently.
Your cat is vomiting, drooling, breathing fast, or acting weak.
Your cat is hiding, refusing food, or seems depressed.
Your cat is a male and has not produced a normal urine clump in 12 hours.
You see blood in the urine along with straining.
Your cat collapses or seems unable to walk normally.

Do not wait for an appointment tomorrow. A blocked cat can go from uncomfortable to critically ill in hours. If you are unsure whether your cat is blocked, call the clinic and describe what you see. Most clinics will tell you to come in right away.

Safe Things You Can Do at Home While You Wait

Home care cannot fix a blockage or cure cystitis. Your job is to keep your cat comfortable and get to the vet quickly.

Do not give any human pain medication. Many are toxic to cats.
Do not give any medication unless your veterinarian prescribed it for this cat.
Do not squeeze or press on your cat's belly. You could rupture the bladder.
Keep your cat indoors and away from other pets.
Offer water and wet food if your cat will eat. Do not force anything.
If you can collect urine, use a clean, dry container with a lid. A plain plastic cup works. Keep it in the refrigerator and bring it with you. Do not delay the visit to collect a sample.
Write down what you saw and when it started. Note the number of litter box visits, the size of the clumps, and any crying or blood. This helps your veterinarian.

If your cat is peeing on you or on furniture, that is often a sign of pain and urgency, not spite. Cats with bladder inflammation may urinate wherever they are when the urge hits. Clean soiled areas with an odorless enzymatic cleaner. Avoid cleaners with bleach or ammonia [6].

What Your Veterinarian Will Check and Test

Your veterinarian will start with a full history and a physical exam. They will feel your cat's bladder and check for pain, size, and firmness. They will also check hydration, heart rate, and gum color.

Common tests include:

Urinalysis. This checks for blood, crystals, white blood cells, bacteria, and urine concentration. It can also find parasite eggs in rare cases [3].
Urine culture. This identifies a bacterial infection and the right antibiotic.
Blood work. This checks kidney values, electrolytes, and overall health. It is especially important if a blockage is suspected.
Imaging. X-rays and ultrasound look for stones, sludge, foreign bodies, and bladder wall changes [4].
Contrast studies. In some cases, your veterinarian may use dye studies to look at the urethra and kidneys [5].

The 2025 iCatCare consensus guidelines describe a step-by-step diagnostic approach because the signs of FIC, stones, infection, and obstruction overlap so much [1]. Your veterinarian cannot guess the cause from the signs alone. Testing is how they choose the right treatment.

Treatment Depends on the Cause

A blocked cat needs a urinary catheter, fluids, pain control, and monitoring. Some cats need surgery. Cats with stones may need a special diet, medication to dissolve certain stones, or surgery to remove them. Cats with infection need antibiotics. Cats with FIC need a mix of pain control, stress reduction, and environmental changes. Cats with parasites or foreign bodies need specific treatment for those problems [3][4].

Your veterinarian will calculate any medication dose from your cat's weight and health. Never use a dose from the internet or from another pet.

Prevention and Monitoring

You cannot prevent every bladder problem, but you can lower the risk and catch problems early.

Feed wet food or add water to meals to increase water intake. Talk to your veterinarian about the best diet for your cat.
Keep fresh water available in more than one place. Some cats prefer a fountain.
Scoop the litter box at least once daily and clean it thoroughly at least once a month with an odorless cleaner. Avoid bleach and ammonia products [6].
Have one litter box per cat, plus one extra. Use unscented litter [6].
Keep the box in a quiet, easy-to-reach spot. A cat in pain may avoid a box near a noisy appliance or a dog.
Reduce stress. Cats with FIC often flare after changes like a new pet, a move, or a schedule shift [2].
Watch the litter box. Know your cat's normal clump size and frequency. A change is your early warning.
Keep routine vet visits. Older cats and cats with a history of bladder problems need regular urine checks.

If your cat has had one episode of lower urinary tract signs, she is more likely to have another. Your veterinarian may recommend a monitoring plan, including periodic urinalysis and weight checks. If your cat starts peeing outside the box again, see Why Is My Cat Suddenly Peeing on the Carpet? and Why Is My Cat Suddenly Peeing on the Wall?. Medical problems and behavior problems often overlap, and treating the medical issue is the first step [6].

Limitations and When to Contact a Veterinarian

This article cannot tell you what is wrong with your cat. Only a veterinarian who examines your cat and runs tests can do that. Individual cases need a veterinarian.

Call your veterinarian the same day if your cat is peeing small amounts more often, has blood in the urine, is licking the genital area a lot, or has started urinating outside the box.

Go to an emergency clinic now if your cat is straining with no urine, crying, vomiting, hiding, weak, or has a firm painful belly. Do not wait.

Schedule a routine visit if your cat had a mild episode that seems to be improving, but you still want a urine check. Even mild signs can be the start of something serious.

Frequently Asked Questions

Should I wait to see if my cat feels better on his own?

No. Small, frequent urination can be the first sign of a blockage, and blockages can become fatal within a day or two. Waiting is the most dangerous thing you can do. Call your veterinarian or an emergency clinic now.

How do I know if my cat is blocked or just has cystitis?

You often cannot tell from home. Both can cause straining and small amounts of urine. A blocked cat usually produces no urine or only drops, and may cry or vomit. If you are unsure, treat it as an emergency and go in.

Can stress cause my cat to pee just a little bit?

Yes. Stress is a known trigger for feline idiopathic cystitis, which is the most common cause of these signs [1]. Changes at home, new pets, and schedule shifts can set off a flare [2]. Stress management is part of treatment, but your cat still needs an exam to rule out a blockage or stone.

Will changing the litter fix this?

Changing to unscented litter and keeping the box clean can help, but it will not fix a blockage, stone, or infection. Litter box changes are part of a broader plan [6]. If your cat is straining or producing tiny amounts of urine, see a veterinarian first.

Can my cat pass a bladder stone on her own?

Some small stones can pass, but others block the urethra and become life threatening. Stones are the second most common cause of lower urinary tract disease in cats [2]. Your veterinarian needs imaging to see the stone and decide on the right treatment.
