There are cat calming products like Feliway.
FELIWAY comforts and reassures cats and kittens, reducing signs of stress such as urine spraying, scratching, fighting or hiding.
As a veterinarian I highly recommend Feliway.
Reduces urine spraying in 9/10 cats. Can see results within 7 days.
Feliway can be used together with calm food or calming collar for more positive results.
