The signs and causes of feline urinary problems and how to care for them at home
Small as it is, the bladder sits at the centre of a complex relationship between stress, biology and environment. If something seems off about your cat’s toileting habits, you need to act early. While feline urinary problems are common, the signs and causes range from manageable to severe. And if your cat needs ongoing care at home, you will have an essential role in their recovery.
At Cat Specialist Services, we provide high-quality veterinary treatment for cats and only cats. Our team understands the health problems they face and the support they need. When it comes to urinary disease, medication might be part of the solution, but it is not the whole picture. What happens at home, including how you monitor, care for and respond to your cat, makes a huge difference.
The signs of urinary tract disease
Changes in toileting habits are one of the clearest indicators that something isn’t right. While some signs may seem behavioural, many point to pain, discomfort or an underlying medical condition.
- Blood in the urine
- Straining or crying while urinating
- Frequent attempts to urinate, often passing only small amounts
- Repeated digging or pacing around the litter tray
- Urinating outside the litter tray
- Seeming withdrawn, irritable or unusually quiet
- Overgrooming the abdomen, genitals or hind legs
- Bald patches from persistent licking
- Signs that resemble constipation, such as repeated straining without result
- In severe cases, leaking or dripping urine while resting
All of these signs require prompt veterinary attention. Some may indicate a life-threatening emergency, especially in male cats.
Emergency alert - urethral obstruction
A urethral obstruction occurs when the narrow urethra becomes blocked and urine is unable to leave the bladder. Because of their anatomical structure, male cats are more likely to experience this medical emergency. Their urethra is longer and narrower than that of females.
What causes blockages? They can be triggered by a combination of factors, including small stones, urinary crystals, blood clots or plugs made of mucus and cellular debris. In some cases, the urethra spasms or narrows in response to pain or previous inflammation, which can worsen or even cause an obstruction.
A cat with a blockage will often strain in the litter tray but pass little or no urine. Some cry out in pain or go back and forth to the tray without relief. As things progress, they may become quiet, stop eating, vomit or seem generally off. When urine can’t pass, waste and toxins build up in the body quickly and then start to affect the kidneys and other organs.
As mentioned, this is a medical emergency. Without urgent veterinary care, urethral obstruction often leads to kidney damage, bladder rupture and death within 24 to 48 hours. If you think your cat may be blocked, don’t wait — have them checked by a vet as soon as possible.
The causes of feline urinary tract issues
Feline Idiopathic Cystitis (FIC) is the most common cause of urinary tract problems in cats, particularly in young to middle-aged adults. It affects both sexes but is the main reason male cats become blocked. While the exact cause isn’t clear, FIC is linked to inflammation, stress and how the bladder and nervous system respond to the cat’s environment. Contributing factors may include a cat’s temperament, excess weight, early life stress or an indoor lifestyle — not as causes on their own, but as part of a broader picture.
Additional medical causes include:
- Urinary stones (uroliths) that form in the bladder or urethra. These can cause pain, blockages and often need to be removed surgically.
- Bacterial infections, which are uncommon in healthy cats but can occur in older cats or those with conditions like kidney disease or diabetes.
- Anatomical abnormalities, trauma or tumours are rare but still possible causes of urinary issues.
Most causes present with similar symptoms, so physical signs alone aren’t enough to identify the underlying issue. That’s why accurate diagnosis relies on thorough testing, including urine analysis, imaging such as X-rays or ultrasound, and sometimes blood tests. Never assume a urinary problem is minor or simply stress-related — the right diagnosis is essential for the right treatment.
“Home care and monitoring play a major role in recovery.”
What you can do at home and how to help your cat feel safe and in control
A cat’s environment plays a significant role in their urinary health. Stress can trigger or worsen issues, particularly in cats prone to FIC. Calm, secure surroundings support recovery and help reduce the chance of recurrence.
Cats feel safest when they have quiet, secure places to retreat to. Raised spots like shelves, cat trees and window seats give them space to rest without interruption. Litter trays should be kept clean and placed in calm areas of the home, with one per cat plus one extra. Outdoor access can also help reduce stress, as long as it’s safe and the cat is comfortable using it.
In multi-cat homes, conflict isn’t always obvious. One cat might quietly dominate another by blocking access to food, water or the litter tray. Give each cat their own space and separate resources. Keep things calm and predictable, and handle them in a way that doesn’t add tension.
To support autonomy, let your cat initiate contact and avoid handling them during periods of stress or illness. Cats prefer predictability, so keep feeding, play and interaction routines consistent. Puzzle feeders and gentle play offer useful mental stimulation. If conflict between pets continues, speak with your vet about behavioural support or further changes you can make at home.
Diet and hydration
Adequate hydration is essential in managing urinary issues. Water helps dilute the urine, reduce crystal formation and support overall bladder health. You can encourage your cat to drink more by offering it in different ways, such as wide ceramic bowls, tall glasses, pet fountains or water from plain cooked meat like unsalted chicken broth or tuna water.
If your cat requires a prescription urinary diet, introduce it slowly. Start by mixing a small amount with their usual, preferred food and increase gradually over several days. Switching meals while your cat is unwell or recovering from a blockage isn’t advisable, as reduced appetite is common and this could lead to food refusal.
It’s important to note that not all cats with urinary signs will need a prescription diet, and these diets should only be used under veterinary supervision. Depending on your cat’s condition and preferences, alternative options may be more suitable. Always speak with your vet before making changes.
Giving medication and taking urine samples
Some cats will need medication to manage pain or support bladder function, but giving tablets or liquid isn’t always straightforward. If your cat tends to resist, speak with your vet about other formulations that might be easier to manage. It’s also worth thinking about how you give the dose. Hiding medicine in their main meal can backfire if they start avoiding food altogether. A treat or a small portion on the side is usually a safer option.
If your cat has urinary tract issues, you will most likely need to complete urine testing at home as part of the management plan.
While vets may collect a sample directly from the bladder via cystocentesis in some cases, there are simpler methods for home use.A clean litter tray with non-absorbent litter works well, and the sample can be taken using a syringe or pipette. Timing matters, and fresh samples are best. You can always ask your vet for a demonstration, or watch our detailed video guide here.

We transported our cat here from another animal hospital, as his condition was too complex for them. Our pet was given the highest quality of care, multiple investigations/procedures being able to be done at the one place a godsend. We were kept up to date frequently throughout his stay. All questions & options explained thoroughly. Being able to have private visits certainly helped us and our cat too. I would highly recommend Cat Specialist Services at Underwood. Amazing staff from reception, vet nurses, vets & specialists. Oh, and yes he is recovering wonderfully at home.

So very happy we were asked to come here for advice for our NORBIT. He has had 2 x UTI blockages within weeks of each other since turning 6. Surgery seemed to be his only option and he didn’t feel it was very fair on him if we didn’t at least exhaust all other avenues first.
Dr Allison was very thorough in her tests and has let us know she would like to treat the cause of the problem. Great news.
It may lead to removal of crystals in his bladder if his diet doesn’t let him pass them naturally.
At least this surgery won’t be as severe at taking his penis off him – so as his fur parents – we are very happy with this.
We await further tests to see what’s in store for him.
NORBIT will now be a patient of the clinic as we are so far very happy with his treatment thus far.

I cannot thank the entire CSS team enough and especially Dr Cindy for the care they provided for our boy with a urinary blockage, and we will be taking both our cats here from now on. The clinic is exceptionally clean and calming compared to all other clinics we’ve been too, and all staff from the reception to the nurses/vets were so supportive during a stressful time. I knew from the first minute that I got to see him after he was transferred that he was in the best place, and that the staff genuinely care about their well-being and positive long term outcomes. We were given regular updates and full transparency, so much information including QR video codes on how to administer medications, along with print outs and emails about how to best help avoid future issues or recurrence. Our boy got to smooch on everyone and was beyond well looked after. Thank you again, you all made an incredibly stressful situation actually manageable and calming.

Dr Alison Jukes from CSS Underwood is an AMAZING feline physician. She is kind, professional, thorough and our cat is blessed to have her on his side. She even was able to save us money and invasiveness by being skilled to the level of doing ultrasound on two separate occasions without our cat needing to go under full sedation. Our other cat was recently seen by Dr Jukes as well, and she made sure our cat’s heart was ok. I also want to thank the lovely Jacqueline and Mairead from customer care. They are very kind each time I see them and call up. Sending thanks from our family, including Smokey and Floozy!

My whole experience with CSS was positive – from the first email I received giving lots of information regarding the process of radioactive iodine treatment to the expected costs, to checking my cat in for the treatment, boarding for 2 weeks after the treatment and picking her up to come home. They didn’t push for any tests that were not necessary.

We never knew this service existed but we are very grateful we were referred to them. Our vet Cindy was really great, she made us feel at ease during a very stressful time. We got the sense straight away the Leo was in good hands. This service made us feel better knowing that they specialise is cats only. Would highly recommend their services

My Lani finished her I-131 treatment today and I am beyond impressed with the way she was looked after. I am by definition a neurotic pet owner and sending my fur child away for a week was seriously daunting.
I was given daily updates about how kitty was eating, toileting and behaving. This really put my mind at ease. Vets and vet nurses were so accomodating and allowed Lani to have her favourite foods from home prepared her favourite way.
Her vet was so thorough when explaining her treatment and condition to me.
The ladies at reception were so friendly and understanding.
I honestly cannot recommend this clinic enough and I am so thankful for the positive experience Lani and I have had.

My sweet ginger boy Louis was hospitalised at CSS for a Urinary Obstruction. Dr Cindy and all the reception staff were amazing and empathetic. I would often ring up with questions post procedure and Dr Cindy would make time to talk and explain things to me
