My cat pees outside the box and vomits. What else can I try?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Mediumhair | Male | neutered | 7 years and 3 months old | 15 lbs

My cat is 7 & is heavy (15# instead of 12/13). The last few months, he's been urinating in the hallway off & on, & he was vomiting occasionally. His vet ran bloodwork (not sure what tests), said everything looked normal. They couldn't get urine. We tried Clavamox, thought may allergy, so switching food to Instinct. I've been cleaning his litter box more, especially since his poop smells foul the last couple days. There's 1 other cat in the house & 3 litter boxes (1 ea floor). What else can I do?

I'm sorry to hear that you are having this problem with Kaivos. There are a large number of reasons that a cat will inappropriately urinate (urinate outside the litter box). I am attaching a handout below which discusses this in detail. https://www.vin.com/veterinarypartner/default.aspx?pid=19239&id=4951508 I do think it is important to get a urine sample on him to make sure you are not dealing with a medical problem. Even if this has been going on for a long time, it is possible that it is a medical problem. If that is normal, then we need to look at other possibilities. It sounds like you have an appropriate number of litter boxes. The handout above discusses litter box issues that can play a role. Make sure the boxes are not covered or lined, and are cleaned daily. You may also want to try products like Cat Attract Litter (https://www.drelseys.com/shop/cat-attract/). You should also look at decreasing stress in case that is playing a role. One option for decreasing stress is to add a Feliway Diffuser ( https://www.feliway.com ) to your house. This is a calming pheromone that will work for a month. I have also had luck with Rescue Remedy ( http://www.bachflower.com/rescue-remedy-pet/ ) which can be added to the water. You could also consider calming music specifically for cats ( http://throughadogsear.com/tace/through-a-cats-ear-1-music-for-calming/ ). If your veterinarian cannot find a medical reason and all litter box issues have been dealt with, then it may be time to discuss medication with your veterinarian. Medications are also discussed in the handout. Good luck! I hope that was helpful. Thanks for using PetCoach.
