Great question! It depends on why Sammy is urinating outside of the box. If it is for behavioral reasons, like marking, yes neutering him could help. If it is for behavioral reasons like stress, no. If he has a urinary tract infection, then neutering won't help. I recommend having a vet examine him first and rule out an infection. If that is normal, I would recommend neutering him for marking reasons. Lastly, I would recommend cleaning the urine with an odor neutralizer because even if you can't smell it, Sammy still can. Good luck and kisses to Sammy!

    Intact males will mark their territory, and will always want to go outside all the time to roam and mate. Neutering will help cut down on the desires to roam, and can help with the urinating in the furniture. It may not remove it completely if he's been marking for a long time, but it is possible it can go away for good. When you take Felix to be neutered, be sure to use a cleaner to get the smell of the urine out of the furniture. You will need a special enzyme cleaner to get rid of it, and they should have products for that in a pet store. Good luck, I hope this helps!

    If he isn't neutered the behavior could be marking behavior. Having him neutered may reduce the number of accidents and marking behavior in the house. Using an enzymatic cleaner to remove any urine can also help as it breaks down urine particles and may deter him from going there again. If you are having trouble affording care, this site may help so that you can have Oliver examined, and treated if there is an underlying illness. Many clinics and shelters also offer low to no-cost neutering programs for low-income families that may be beneficial: http://www.humanesociety.org/animals/resources/tips/trouble_affording_veterinary_care.html

    Neutering a cat can reduce making behavior, but it could also be a medical reason behind why Elsa is peeing outside the litter box such as feline idiopathic cystitis or bladder stones to name two causes. Have him seen by a vet to discuss getting him neutered, and the vet can also diagnose if he has one of those things I mentioned above. Best of luck, I hope this helps!

    This is a frustrating issue and the number one cause for pets being rehomed. Neutering will help, but it likely will not be a cure all for this issue. First, have the little guy seen by your veterinarian to rule out urinary tract infection, inflammation or other medical issues that could be causing his frequent urinating or marking. Next, clean the boxes daily and try different types, amounts and brands of litter. He may have a substrate preference. Restrict or prevent access to areas where he is urinating. Use an enzymatic cleaner, such as Nature's Miracle ( https://www.petco.com/shop/en/petcostore/product/natures-miracle-new-formula-just-for-cats-urine-destroyer-stain-and-residue-eliminator ), to thoroughly clean soiled areas. Provide additional litterboxes if necessary. The rule of thumb is one box per cat plus an additional box in a "neutral" area. Try both covered and uncovered boxes. Lastly, consider a pheromone product, such as Feliway spray of diffusers ( https://www.petco.com/shop/en/petcostore/product/feliway-classic-30-day-starter-kit-plug-in-diffuser-and-refill-for-cat ), to decrease any stress or anxiety in the home. Be sure to have enough to cover your entire house. https://www.petcoach.co/cat/condition/inappropriate-urination/
