This stuff has helped my anxious kitty so much. It has a bit of a funny smell but you soon get used to it and don’t notice it anymore. The difference is amazing and it’s worth every penny for my cat to be happy and confident. It’s helped 2 cats get on better as well. I wouldn’t say they were best friends but they’ll both lie on the bed at the same time now and there have been a few nose bumps on good days.
