All cats, male or female, neutered or not, will mark out their territory with urine spraying. Normally this is rare and discrete. But when this natural behavior happens in your house, it can be very frustrating. When this happens, it is due to fear and anxiety.
It can be a reaction to:
Recent changes at home
New home or new furniture
New cat or kitten, or a new dog
New family member, baby, etc.
Conflict with other cats:
Competition for access to litter box
It can also be caused by a medical issue. If your cat starts peeing outside the litter box, please consult your veterinarian. Especially older cats, who are at risk of more medical issues.
Using FELIWAY Optimum Diffuser continuously may help stop and prevent spraying, especially if your cat seems emotional and sensitive to any change at home.
