Review on 🐱 TropiClean Natural Flea & Tick Repellent Collar for Cats - One Size Fits All – Waterproof, Breakaway Design – Provides Up to 4 Months of Flea & Tick Protection by Todd Look

. Not sure if it works, although it might! (We will never go back to "poison flea and tick collars" - we did this last year and our cat had a horrific reaction that took months to recover from.) We don't live in a heavily flea infested country Area. . Our cats are fine, no signs of ticks or fleas. Most importantly, none of our three cats who used this collar had any major reactions. That's a relief. We use essential oils for ourselves, so we are already convinced of their effectiveness. It's been over 2 months since they were added to our favorites, so maybe it's working! We would buy again.
