My cat sprays bedroom walls, is it stress from other cats?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 11 lbs

My two-year-old cat has had a peeing issue for as long as I can remember, he had a UTI when we first adopted him and took him to the vet to resolve it. I thought the peeing would stop, here and there I would find wet spots on the carpet, clothing or on his bed. He uses his litterbox as well. Recently he is now living with two older cats who do not like him very much, he now sprays my bedroom walls only, nowhere else around the house, but he still continues to use his own litterbox as well.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Loui. That must be so stressful for you! If he's living with other cats who do not like him, that will stress him out. Most urinary tract "infections" in non-geriatric cats are not caused by bacteria (antibiotics kill bacteria) but inflammation caused by stress. This is called feline idiopathic cystitis. Male cats also seldom have a bacterial cystitis as the urethra is much longer than a female's urethra and therefore bacteria would have to travel much farther to get into the bladder. It could be he has feline idiopathic cystitis, so I would take him into the vet. If he does have it, the vet can prescribe prednisone. It takes the inflammation which in turn takes the pain, and it is also a diuretic which helps flush the bladder. I hope this helps!

Why is my cat still urinating outside of the litter box even though he just got treated for a UTI around three weeks ago? I have tried feliway for stress and that hasn’t been helping. I also bought him a second litter box and ever since then he hasn
Some cats are very sensitive to change and stress and can develop urinary issues because of it. There are also calming food and treats that you may consider trying, Hills and Royal Canin both offer excellent diets for this. He may need time to settle in, he may need further medications to ensure his UTI is cleared, it may have recurred because of the stress of travel, he may have a condition called Feline idiopathic cystitis. This is cystitis or an inflamed bladder which has an unexplained medical cause. It is a common condition and is not normally a serious health concern, but can be very uncomfortable for your cat. FIC is more common in younger felines and episodes tend to resolve as they get older. FIC is different from a bladder infection, bladder stones or more serious urinary tract conditions, but can often present the same symptoms. I recommend getting him back in to see your vet and discuss these possibilities with them.

My male cat was neutered two years ago. When he was fixed he was no spraying. A few months after the surgery he started spraying. What can we do to stop him? He sprays the walls not furniture
Hi and thanks for using Boop by Petco! Sorry to hear about Rabbit. Spraying can be due to a medical or behavioral problem. Good news is that both are treatable. Medical problems are usually due to cats developing Feline Lower Urinary Tract Disease or Syndrome, also known as Feline Interstitial Cystitis. This has many causes including stress, infection, urinary crystals/stones which all lead to bladder inflammation among other changes including spraying. I would advise making an appointment with your veterinarian so they can examine him and perform some tests including a urinalysis to see if there are signs of a medical problem. Sometimes blood tests are required to make sure the kidneys and internal organs are functioning properly. Once a diagnosis is made there are various ways to treat this including drugs to treat the stress, infection (if any), and the inflammation. Sometimes a special diet is advised if crystals are present. Or even surgery if urinary stones are actually prese

Is it actually possible for a cat to have urinary issues with allergies? I took one cat in for a possible urinary tract infection. After bringing him home (where the vet said it was allergies) I noticed my other cat had similar symptoms, only she cou
A true urinary infection with bacteria is much less common in cats then dogs, and less common in males then females. Unless there is a disease process predisposing to infection like diabetes or kidney disease. I would not expect a link between allergies and urinary issues unless as you say it is stress related. There is a syndrome in cats (many names) called feline lower urinary tract disorder (FLUTD). Basically it causes symptoms of a uti but there is no infection. In can be more problematic in males. It could be triggered by stress (changes in the house, change in litter, new food, not enough litterboxes, etc.). The Ohio State University has a good web site for indoor cat owners called the indoor pet initiative. There are other causes of urinary tract issues as well but it would be quite odd for both your kids to be affected. It is very important to make sure cats are able to urinate though because obstruction of the urinary tract can occur, more common in males, and this is an emerg

I have had Luna a little over 2 years and we have been fights with peeing on my bed and clothes. She has recently started back up 2 days ago and has peed 2x. Idk if it could be a UTI(has them in the past) or another issue, we have a another cat she
It certainly could be another problem with Luna's urinary tract, like feline idiopathic cystitis. Having another cat in the house is stressful, and that can lead to this cystitis. I'd have her seen by a vet to have this diagnosed and treated. I'd also get your male cat neutered. I hope this helps!

My cat is urinating on the floor and on vertical surfaces . UTI is gone and he gets along with my other cats. I'm not sure what to do or if there is a serious issue
Urinating on the floor and vertical surfaces is a sign of anxiety and most likely not a continuation of the UTI. There can be several reasons for his anxiety, including not enough litter boxes (you should have 1 per cat 1), recent change to the home or a recent move, or a recent addition to the home. I would start by trying anti-anxiety medication through your vet. I have the most success with Fluoxetine given daily for 2-3 months, coupled with behavioral modification training. There are many tips on how to make your home environmentally sound as well. The website link for those tips are: indoorpet.osu.edu jacksongalaxy.com Other conservative treatments that may help are: 1) Feliway plug-ins 2)Zylkene powder- available online and a natural medication to treat for anxiety in pets, especially marking behavior. Best wishes with Kai and I hope that you find something that works for his urination problems soon. Take care. Here is more information on urine marking in cats. http://www.

Hello, After rescueing a kitten 5 months ago, our older cat has been spraying more often than usual. The last time he sprayed blood when we moved house the vet said it was a self induced UTI. He’s always been a grumpy cat that sprays and hisses ever
Urination outside the litterbox and blood in the urine can be caused by stress or behavioural issues, but can also be due to urinary tract infection, crystals in the urine, stones in the urinary tract, toxin ingestion, coagulation disorders, or trauma to the area. Another cause, which you referenced, is idiopathic cystitis or Feline Urinary Tract Disease, which can cause the symptoms you've noticed and can be triggered by stress. It is important that you make an appointment to have Keiko seen by your veterinarian immediately to help determine the cause of his behaviour and to start treatment. If you notice him straining to urinate/unable to produce urine, this is a medical emergency and he should be seen by a vet immediately. Pain medications meant for humans can be very dangerous (and even deadly) for cats, so I do not recommend giving any to Keiko without consulting with your vet. If medical causes are ruled out, it is possible that Keiko is exhibiting signs of stress in his

Hello, thank you for using Boop by Petco. I cannot tell you for certain whether the spraying is associated with the current urinary issue or if it is a behavioral issue. If I had to guess, I would say it is likely related to his current medical situation. You need to talk to your vet about this as they have all his medical information that I do not have. I'm also assuming he has bladder crystals and not stones? If he has stones then he would need surgery to remove them and that may be why the urinary is bloody. You need to clarify that with your vet. Please take Miu Min back to your vet for a follow-up and to discuss.

Poor Spook! If this behavior only occurs when you have visitors in the house, it may be related to stress or anxiety - urine marking is a common response to stressful situations for many cats. Spook may also have a medical issue causing her to urinate inappropriately on things, such as a urinary tract infection, bladder stones, or FIC (feline idiopathic cystitis). I would recommend having her examined by a vet as the first step in addressing this problem, since if she has a medical issue, this will need to be treated appropriately in order to make any progress at stopping the behavior. If her exam and lab work are all normal, you can also speak to your vet about whether she might be a good candidate for anti-anxiety medication - many cats with inappropriate urination related to stress respond well to SSRIs such as Prozac or similar medications. You could also try a Feliway diffuser along with a natural calming supplement like Zylkene or Composure to see if this helps.

Our 3 year old cat keeps spraying around our home. This is new behavior as far as repetitiveness, he’s doing it a couple times a week now. It started around winter time, and he loves to be outside, could that be it?
It can be a behavioral sign of stress or frustration. If he enjoys outside and is not getting to go outside, then this can definitely contribute to it and he is acting out. If there is another cat in his area outside that he sees it will also make him spray to mark his territory since he can't get to the area outside. You can let him out more, or try feliway plug ins and diffusers to help keep him calm. I would also get a urine sample checked to make sure the is no infection that is causing it.

Causes of urination outside the box can be urinary tract infection, crystals in the urine, stones in the urinary tract, trauma to the area, or difficulty getting into the litterbox due to pain, or other reasons. It is important that you make an appointment to have Moon seen by your veterinarian as soon as you can to help determine the cause of his behaviour and to start treatment. If you notice his straining to urinate/unable to produce urine, this is a medical emergency and she should be seen by a vet immediately. I highly recommend speaking to your vet about having Moon neutered, as this kind of behaviour can happen in male cats as a form of marking behaviour, and sometimes having them neutered can help reduce or eliminate the marking. It is also possible that Moon is exhibiting signs of stress in his home environment. You can do the following to help make sure Moon’s environmental needs are being met. Cats need at least one litterbox per cat plus one extra to help reduce stress
