What Does Cat Spray Smell Like? Vet-Reviewed Facts & Behavioral Reasons

If you’ve ever seen your cat back up to a wall, the couch, or anywhere that is a vertical surface and spray urine, it’s called urine marking or spraying. Sometimes, they spray on a horizontal surface, but most of the time, it’s on anything vertical. Cat spray smells quite strong and pungent due to the presence of volatile organic compounds (VOCs) produced by the cats as a means of communication. Cat spray has a strong ammonia odor, which is more intense than urine. Scent-marking is common in animals, with the scent cues remaining in the environment for a relatively long time, even in the absence of the animal, making it very valuable compared to visual or auditory cues.

How Bad Does Cat Spray Smell?

Well, it’s not great. You can identify cat spray by an overwhelming ammonia odor mixed with other pungent chemicals. Unlike the urine smell from the litter box, the spray has other chemicals that provide data to other cats.

Some pet owners think it has a sulfur odor, but the smell will vary, depending on the cat. You’ll smell ammonia more than anything else, but the spray will also have a musky scent. When marking, cats deposit less urine than when urinating.

Why Do Cats Spray?

There are various reasons that a cat sprays, and while female and male cats can spray, it’s mostly unneutered male cats that do it. We will talk about why cats spray below.

1. Conflict

A cat will spray if there is any conflict in the household. For example, if you have multiple cats in your home, they may spray to establish boundaries and even to settle feline arguments. If one of your cats shows dominance over the others with the food or litter box, they may start spraying certain areas. Buying another litter box or two so the competition ends may solve the problem, or you can feed the cats in separate areas to end the conflict over the food bowl.


2. Territorial Marking/Mating

If your cat hasn’t been neutered or spayed, they may be spraying around your property to attract a mate. Neutered or spayed cats can still spray, but it’s rare. Cats mark their territory by spraying to show competitors that your home is part of their range, and they also spray to attract the opposite sex. They target vertical surfaces because the smell is easier to detect there than on horizontal ones. Cats will continue to spray to attract nearby felines unless they’re neutered or spayed.

3. Additional Causes

There are a few other reasons that your cat could be spraying, including moving the cat to another house or putting them in a stressful situation. Stress can cause a cat that didn’t spray before to begin spraying everything in the house. If your cat is stressed, try to find the cause to resolve the issue.

For instance, if you just moved, ensure your cat has a quiet room to enjoy their bed, cat tree, and toys. Spend more time playing with your cat and try to keep the same feeding schedule as you did at your old home. After a few days or weeks, your cat should become more comfortable with the environment and hopefully stop spraying.

The pungent aroma from cat spray can overwhelm your senses and harm your loving relationship with your cat, but there are a few ways to end the spraying.

  • Have your cat neutered or spayed.
  • Provide enough food bowls and litter boxes (one for each cat, plus one) for all your cats.
  • Spend more time with your cat and comfort them in their new home.
  • Build a catio or similar if you keep your cat indoors all the time.
  • Take your cat to the vet if it displays other troubling signs.
  • Clean up cat spray with an enzymatic cleaner to prevent accidents in the same spot.

Conclusion

Cat spray has an extremely pungent smell that is hard to miss. While it may look like your cat is urinating on the wall, they’re actually releasing powerful urine with volatile compounds that work to communicate with other cats. If your cat is spraying and you can’t get them to stop or find a reason for the behavior, it’s best to make an appointment with your vet to determine the problem. Your cat may be stressed or sick, or maybe you just need to have them fixed to remedy the situation.
