My neutered male cat sprays walls. Why and how can I stop him?
Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Rabbit. Spraying can be due to a medical or behavioral problem. Good news is that both are treatable. Medical problems are usually due to cats developing Feline Lower Urinary Tract Disease or Syndrome, also known as Feline Interstitial Cystitis. This has many causes including stress, infection, urinary crystals/stones which all lead to bladder inflammation among other changes including spraying.
I would advise making an appointment with your veterinarian so they can examine him and perform some tests including a urinalysis to see if there are signs of a medical problem. Sometimes blood tests are required to make sure the kidneys and internal organs are functioning properly. Once a diagnosis is made there are various ways to treat this including drugs to treat the stress, infection (if any), and the inflammation. Sometimes a special diet is advised if crystals are present. Or even surgery if urinary stones are actually present depending on the type of stones and how big/how many there are. Behavioral problems are assumed if the medical tests come back normal. These problems can be addressed with some medications in the hopes of decreasing/stopping the urine spraying. One last thing, if it's medical and a lower urinary problem, male cats can block with this disease which can prevent them from urinating. If you notice no urine production, get him evaluated immediately. Good luck with Rabbit. I hope this resolves soon.
