Why is my cat straining in the litter box but not peeing or pooping?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 11 years and 2 months old | 16 lbs

My cat goes to the litter box, digs a bit, then squat down like he wants to pee/poop, but he doesn't actually go. Then he'll walk away, sit for a bit, then return and do the same thing. What's wrong with him and how can I help?

Oh no, that's not good. This can be a sign of a blockage in the urethra from bladder stones. A urethral blockage is fatal without treatment, and since I can't see Mittens in person to rule one out, I think it's best to take him into a vet now. Please take him into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.

    If Pepper is straining to urinate, this can be a sign of a urethral blockage. A urethral blockage is fatal without treatment, and since I cannot see him in person to rule this out, he has to see a vet now. Please take him into one immediately.

    Thanks for using Petco Pet Education Center, formerly Petcoach. I would take Julie in IMMEDIATLEY to your vet or the nearest emergency vet. She is showing signs of being blocked. This is much less common in females than in males but it is life-threatening either way. A feel by a vet or an experienced tech can help determine right away if she i blocked. The other, more common reason for these signs would be a urinary tract infection or other lower urinary tract disease. Best wishes to you and Julie!

My cat is struggling to go to the bathroom. The last few weeks he has peed in the closet several times, with never a problem prior. He is crying out/ meowing while he tries but nothing comes out.
This is a medical emergency and Earl Grey has to see a vet now. He may have a blocked urethra, which is fatal without treatment.

My cat has not been peeing for the past day and a half and is now yowling in pain and sitting at the litter box not peeing. I know these are signs of a UTI but not sure what to do about it as we cannot afford the cost for a vet. We have used a liquid
It sounds like he has a urethral blockage so he needs to be examined by a veterinarian right away as this is an emergency and can be life threatening if not treated immediately. You could call your local humane society and see if they can help or try to find a vet that would take a payment plan. Some vets accept Care Credit so you could apply for that. This is a very serious problem and your cat needs to see a vet immediately! I hope you can find a way to get him treated!

Hi there and thank you for using Boop by Petco to address your concern. If Sylvester is in that much distress, I would get him in to be seen by a veterinarian sooner rather than later. What you are describing could be an indication of a fecal impaction, megacolon or something causing an obstruction. If he is not producing any urine either, he may be dealing with a urinary tract obstruction, which can be very serious if left untreated. I would get him seen as soon as possible if you can so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

My cat is 9 and he’s crying and trying to use litter tray but nothing happening
I would be concerned if your cat is straining that he may be obstructed. Urine will not be able to exit the body thusly and will result in your cat becoming very ill very quickly. This is a medical emergency and Dizzy should be seen immediately to be sure this isn't the case. If it is, they will need to intervene and relieve the obstruction. Best of luck.

Last night my cat kept repeatedly going to toilet nothing comes out. She then rubs her bum on carpet and licks for 10 mins then going back to litter tray. She repeatedly did this for 3 hours last night.
Hi, thanks for using Boop by Petco! Poor Martha! I am not sure if you are referring to trouble urinating or defecating. If she is squatting to poop and nothing is coming out then she is likely constipated. Constipation in cats is not a primary condition but a symptom of something else (intestinal disease, kidney disease, etc). She should go to the Vet for an exam, a belly X-ray and have her anal glands checked. If she is severely constipated an enema may be needed. Also at age 9, I recommend blood work be done to check her thyroid and kidney values. Constipation in cats can be managed with diet and stool softeners. If she is straining to urinate then she could have a UTI, crystals in her urine or bladder stones. This also requires a vet exam. Try to prevent her from using the litter box for several hours before her appointment so the Vet can collect urine to test. Crystals and a UTI are diagnosed from a urine sample and bladder stones are diagnosed from an X-ray. Crystals are treated

I notice that my cat is using the litter box more often today, it would sit there for 10 minutes then stop, lick it's bum and right back to the litter box, I checked if it's using it but nothing comes out. is my cat fine? Also my parents bought premi
Poor Hiro! This could be a urinary tract infection or he could be blocked meaning he is incapable of urinating. The latter is an emergency. Since you haven’t seen anything come out, I would recommend to have him seen as soon as possible. Your vet will be able to determine whether he is blocked or just has a bad infection and get him started on the proper meds and treatment. I doubt this has anything to do with the food l, but if he is blocked or starts having chronic issues with his urine, the vet may recommend a special diet for him. I hope this helps!

My cat is straining to go to the bathroom. She hasn't used the bathroom in 5 hours. I don't know if I should take her to the emergency vet or wait until the morning. I don't have the money for the emergency vet. What can I do? If she has a urina
This may sound odd, but luckily she is a female. Male cats can develop an obstruction of the urethra relatively easily, as the urethra is very narrow and can get plugged with inflammatory cells, debris, stones, and the swelling of the urethra itself can become obstructive. A urethral obstruction is an emergency, because life threatening electrolyte abnormalities can start to occur that can result in cardiac arrest, also the bladder can actually rupture. Having said all of that, this problem is rare in female cats. Its possible that a stone could get lodged in the urethra, but their urethras are shorter and wider than that of male cats so we just don't see it much at all in females. She very well may have a significant amount of inflammation in her urinary tract that is making her feel like she constantly has to go even when shes not producing anything. My best recommendation would be for you to try to palpate her bladder at home. When you put your hands around the back part

My older cat is having odd bathroom habits lately. I have two litter boxes in my house and he goes in one and does his business, and not even 10mins later goes to the second box and uses it also. After he is done in there goes back to the first box a
Poor Oreo! Straining in the litter box can be caused by constipation, diarrhea, or urinary issues - it's often quite difficult to tell if a cat is straining to pee or poop, so it can be hard to differentiate these things if you aren't used to looking at them. The most concerning possibility is that Oreo may have a urinary obstruction, especially if you have not seen a significant amount of urine in either box since yesterday. This is unfortunately a very common problem in male cats, because their urethra is extremely narrow where it exits the penis - this area can often become "plugged" with crystals or mucus from the bladder. Signs of this problem include repeatedly going to the litter box without producing much urine, crying when trying to urinate, and often lethargy, decreased appetite, and vomiting. If he does have a urinary obstruction, this is a life-threatening emergency that needs immediate treatment, as the bladder can rupture and cause death within 24 hours in some cas

This is absolutely an emergency. It sounds like he has a urinary obstruction and not just a UTI. Please take him to a vet immediately! Do not give him any medications at home. ( https://veterinarypartner.vin.com/default.aspx?pid=19239&id=6465677 )

My cat has been weak and lethargic for the past 2 days, sleeping for the most part, and since last night has remained in the same spot. I noticed weird behaviour a couple days ago when it looked as if he was trying to poo, he would scratch the floor
Poor Fred! From what you're describing, I'm very concerned that he may have a urinary obstruction. Straining to urinate can look very similar to straining to poop, and is unfortunately a common problem in male cats. This is a life-threatening emergency that often causes symptoms like lethargy, weakness, repeated straining to pee, abdominal pain, loss of appetite, and sometimes vomiting and crying in pain. This is an emergency because the bladder can rupture and toxins will rapidly build up inside the body, resulting in death within a matter of hours. I would strongly recommend getting Fred to an emergency vet immediately - he/she can palpate his abdomen to confirm the problem, and pass a urinary catheter to relive the obstruction.
