Review on 🐱 Mercola Cat & Kitten Herbal Repellent Collar by Reginald Hamilton

I had high hopes for this but unfortunately it didn't work and I had to buy a treatment place to get rid of the fleas. Can't say positively, but I don't think my cat had a shelter when I first dressed her. So not only didn't it stop them from running away, but it didn't stop them from appearing either. I only give it two stars because it doesn't contain any toxins. I will say that my cat spends about 95% of her time outdoors and we live in a country surrounded by deer who will most likely run away from an infestation. May be more effective for indoor cats.
