Why is my unneutered male cat spraying after a fight with another cat?

If Tango is not neutered, this needs to be done. Males who are not neutered spray to mark territory and neutering them tends to stop the behavior. Some neutered males do still spray and this can be related to infections in the bladder or stress. Veterinarians will examine the urine of these cats to look for infection and provide correct treatment. There is treatment available for infections and stress but you have to determine which one is the cause. I hope this is helpful and please feel free to post any additional questions.

It certainly might. Urine marking is a normal and expected behavior for intact males, so neutering is one of the first things we recommend if your cat is doing this. The earlier it's done, the better - this is because the longer this behavior continues, the more it will become a habit that may not resolve after the neuter. It's important to realize that urine marking can also be related to stress or anxiety, so if this is the case, these issues would also need to be addressed in order to resolve the behavior.

No, there isn't. If you have multiple cats, keep a litterbox per cat plus an additional box in a "neutral" area of the house. Try litterbox attractants. You can find them in most pet stores or at www.pet360.com. Consider pheromone sprays or collars to decrease any stress or anxiety. If he can see out a window, draw the blinds to restrict his view. He could be seeing an outdoor cat that he perceives as a threat. Use a small animal repellent along the border of your property. Use an enzymatic cleaner such as Nature's Miracle to thoroughly clean sprayed areas.

This is probably behavioral spraying. I suggest you refer to this link for more information. Basically doing some environmental enrichment and adding more litter boxes with different types of litter in them would be helpful. If you could obtain some Feliway diffusers I would also use them.

As a starting point, make sure that both of your cats have been neutered, as intact male cats will often spray urine due to hormone influences. If both cats have been neutered, the spraying behavior is likely a sign of stress and anxiety, but medical causes of inappropriate urination should be ruled out by a visit to the veterinarian. Separating the newly adopted cat and only allowing the cats to interact under direct supervision may minimize fighting behavior. Also, utilizing calming pheromone products for both cats, such as the Comfort Zone® Multi-Cat Diffuser, may decrease the stress level for both cats. If the aggression continues, consultation with a specialist in [veterinary behavior](http://www.dacvb.org/) to get to the root of the aggression, coupled with prescription anti-anxiety medication may be helpful for both cats.

Intact male cats often spray in the home due to elevated testosterone. Instead of isolating him, which will only make him more anxious and likely to spray more, I would suggest getting him on anti-anxiety medication through your vet. Fluoxetine can work well for cats that spray in the home and can be used up 1-2 months after his neuter, which is the typical time it takes for all the testosterone to diminish in the body. You can also consider moving him neuter surgery to an earlier date. I hope this helps and best of luck getting Mochi to stop spraying in the home. Take care.

This is a normal territory marking behavior and may be triggered by new cats in the area, changes in the routine or layout of furniture and puberty. It does reduce in many cats as they become used to a routine, territory and neighborhood cats (even in indoor cats they are influenced by scents from outside). Neutering would likely help to reduce the behavior
