Review on 🕶️ Hartz Ultra Guard Reflecting Flea & Tick Cat Collar Review: A Reliable and Stylish White Collar for Ultimate Protection - 1 Each by Melissa Brewer

I used this as a backup until something else came along that I ordered. It worked. I would not use it as my only supplier for flea removal. It's really good for the price. Please note that you will need to stretch as instructed to activate this. When activated, the line in the collar becomes lighter. If I hadn't read it, I would have thought it was enough to take it out of the plastic packaging it came in. The work activated him to the fullest.
