Health & WellnessMy cat marks everywhere. Is NaturVet No Mark safe for cats and humans?
Yes it should be safe to use. I don't know how well it will work though. I think you should try some Feliway diffusers and get a second litter box with a different type of litter to put in a different location. He may not like the one you are currently using. Also, if he is not neutered, having that done will often stop urine marking.
