Bests & Worsts Reviews from Amazon

This flea collar made my cat SICK! Initially I thought she just needed to get used to it. A couple days later I noticed she was not her usual playful, energetic self and was really tired and irritable and kept scratching at her neck. The very next morning I saw that she had been vomiting. Once I took the collar off of her I noticed that the collar was HOT to the touch and so was her little neck. She’s fine now and back to being her normal playful, annoying self. But this collar made her extremely tired and lethargic, irritated her skin around the neck and made her vomit. Would not recommend this product!
