My cat is sneezing with discharge after surgery. Is it serious?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 9 years and 3 months old | 9 lbs

Dr. Melanie: Hi! I'm taking in kitty next week for the recheck bld test but I'm a lil worried about her because she's sneezing quite a bit and her nasal discharge increased. I'm worried about pneumonia and possible liquid in her lungs when I gave her her meds even though I didn't tilt her head back . I know anesthesia can cause sneezing but this is day 3 post surgery..

Hi Laila! It could simply be she has a respiratory infection, and I wouldn't get too worried about pneumonia just yet. Signs of pneumonia include labored breathing, loud respiratory sounds, lethargy, reduced appetite, and fever. If she doesn't have those signs as well, I would be more suspicious she has a respiratory infection. I can give you some things to try at home for Kitty. First, you can try starting her on an L-lysine supplement - this is an amino acid that has been shown to help the immune system fight off respiratory infections more effectively. Enisyl and Viralys are both good brands, and can be purchased over the counter without a prescription - just follow the dosing instructions on the label based on your cat's weight. If she's congested, you can also try using a humidifier or bringing her into the bathroom with the door closed while you take a hot shower - the steam and humidity help to break up congestion and temporarily relieve symptoms associated with respiratory infections. Now if she does develop any of the signs I listed above, then I would be concerned about pneumonia, and in that case, I would take her into a vet right away. Best of luck, I hope this helps!

My cat izzy just got de-sexed nearly a week ago now, after surgery she has been coughing, wheezing and sneezing alot i have been given some antibiotics but she is the same and now she has just sneezed out a little bit of blood, is this normal? And sh
If the upper respiratory signs were caused by a bacteria and not resistant to whatever antibiotic she is on, then it should be starting to get better. I would probably have her looked at again. Most likely she was starting to come down with the upper respiratory infection and then the surgery dropped her immune system a bit. It can be common to see this after a stressful situation. They may need to prescribe a different antibiotic or try and culture the nasal passages to try and determine a good antibiotic. Put her in the bathroom with you while you shower and let the moisture help her nasal passages too. It can help

I just had my cat spay like 10 days ago - since that time she has developed sneezing. She didn't sneeze at all last spring and summer so I was wondering if could be allergic to something that had to do with the spay? Or something else? Maybe she ju
More then likely she is having a flare up of an upper respiratory virus with the stress of surgery. Most cats are exposed to these viruses, such as cat herpes, and stress can elicit a flare up. Sneezing, runny eyes/nose, congestion, etc. are common. If there is any discoloration to any discharge, cough, or she is not eating well a recheck with your vet is indicated. For most cats however the signs will run their course in 5 to 10 days. I hope this helps and thank you for using Boop by Petco!

My cat keeps sneezing today but is acting normal and her appetite is normal, concerns? She was under anesthesia 3 days ago for a deep ear cleaning but is acting like herself.
Hi, As long as your cat is otherwise acting normally monitor the sneezing. If the sneezing frequency increases or the cat sowing other signs such as reduced activity, reduced appetite, discharge from nose then take him to be examined by your vet. Also monitor the environment for any changes in common irritants that can effect cats and cause sneezing including cigarette smoke, household cleaners, changes in cat litter etc.

Hi there! About 5 days ago my kitty started having some yellowish discharge in her left eye and then it started a bit in her other eye. Discharge has lessened and she is also sneezing a bit with clear nasal discharge . Appetite and energy level about
This sounds like she has a mild upper respiratory infection, or a cold. While this usually will improve without treatment I would not have the dental done on Wednesday. Her cold could spread to other cats in the hospital. The anesthesia and stress may make her cold worse too. I would reschedule for two weeks, she should be fine then. Thanks for using Boop by Petco to help you care for Kitty.

Hello! My cat William had a very invasive surgery six days ago to remove foreign objects from his stomach and intestines. He is on antibiotic medication and I just brought him home today from the vets. Since he has been home tonight he has had a very
Poor William. He has gone through quite a lot and his immune system must be run down, so he has probably picked up a virus. I would not worry too much at this stage, maybe when your vet opens give them a ring give them an update and ask them what they suggest you feed him.He is already on medications so those will help bacteria at bay, it is important that he starts eating perhaps you could offer something bland but equally quite strong smelling such as boiled white fish or tuna in water. Hope all goes well.!

These may be signs of a upper respiratory infection or tracheal irritation if she was intubated for her surgery. Either can cause inflammation in their throat and affect their sinuses. IF this pattern is still occurring, then i would have your vet rechecked. SHe is likely already on an antibiotics since she had an infection prior to the c section, but they can add medication to help with the sneezing and coughing/retching to help her comfort and recover.

My kitten was spayed a week ago and although her stitches seem to be healing, she has a lump under the area that as stitched and her skin around it is a bit red. The lump decreased in size for the first two days but for the past two days after it's b
This lump under the incision area could be a local tissue reaction to the internal sutures. If it isn't bothering Mimi, not getting bigger, and you don't see any signs of infection, I would not be too worried about it. Keep an eye on it, and if it gets bigger, the area appears infected, or it doesn't go away in a couple of weeks, I would have her checked out by the vet.
