Every cat is an individual, and their behaviors will vary. However, urine spraying in male cats tends to be associated with sexual maturity. Therefore, male cats may start spraying as early as 6 months old as their testosterone levels start rising.
If your cat is neutered at a young age, they’re less likely to spray because they don’t have the motivation to find a mate. However, other behavioral causes of spraying are possible, and inappropriate urination can sometimes indicate a medical condition like feline lower urinary tract disease.
So, if you and your cat are struggling with spraying issues, speak to a veterinarian or a certified animal behaviorist.
