Cat vomits hairball and colored fluid after treats. Should I worry?

Updated On September 23rd, 2025

Pet's info: Cat | Ocicat | Female | spayed | 13 years and 10 months old | 11 lbs

I give my tabby cat 2 cat treats (temptation chicken for indoor cat for hairballs. After breakfast, after lunch and when my son comes home from work. Lately after she has her treats she throws up some a hairball along with some fluid the color of the treat. Should I be concerned or is there something else we could give her. We feed her Science Diet for cats under 6 that has hairball control. We be moving her up to food for cats over 7 when we finish this bag. Thank you, Carolyn Baker

She is obviously grooming a lot and therefore ingesting a lot of hairs. It is good for her to either poop out the hair or even regurgitate the hair balls. I think you are doing everything right and I would not change her food regimen. You can help her a bit by combing or brushing her coat and removing loose hair. This would reduce hair ingested. Please let me know if you have any other questions or concerns and I would be more than happy to help you further. Please take the time to mark this question as helpful or not as it helps us to improve on the quality of our answers to other pet owners. Thank you kindly!

    If your kitty is gagging and coughing and trying to cough up or regurgitate a hairball, you should get some hairball remedy from your vet or a pet shop and feed this to him. This will help with eliminating hair balls. Some cats like the paste and lick it off your finger , others don't like it, so you will need to put it on her paws, so she will lick the paste off cleaning herself. If this does not work, you will need to take Princess to your vet for an exam. Brushing Princess everyday will help with getting rid of loose hair, so that she does not ingest as many when grooming.

    Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Many times, vomiting can be directly related to the diet or an imbalance of the normal bacteria in the GI tract. I would recommend switching to a different food and consider a hairball supplement such as Laxatone. I would recommend Science Diet or Royal Canin for the food to switch to. I would try the Laxatone and new diet for at least 4 weeks. If there is no improvement, I would then recommend adding in a probiotic such as Purina Fortiflora, which can be found quite easily online or at your local PetCo. If there is no improvement after all of this or it worsens, I would recommend having a veterinarian examine her so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

    Given that her form is otherwise good and you have seen evidence of hairballs I recommend you treat her for these with an over the counter paste designed to reduce the build up of hair; a fiber and probiotic supplement such as fortiflora may help also. Regular use of hairbal paste as a prevention is recommended in cats which are prone t episodes. If she is overgrooming, a full physical exam in order to rule out any medical causes or sources of pain and discomfort such as early arthritis may be worthwhile
