I let a feral cat inside and he peed everywhere and eventually my cat did too. And nothing worked! I think my fraustration took a toll on our relationship because she was hiding more 🥺 . Well my vet recommended this stuff and wow! It worked right away! She doesn't pee on the carpet anymore 🙂 and our relationship is mended she is just as snuggly as she was in the beginning. She's happy with me.
