Review on Hartz Ultra Guard Flea Tick by Ryan Bennett

My indoor/outdoor cat hasn't had any fleas since I put the collar on (making sure it's as loose but secure as possible). If the collar is too tight and the insecticide only presses on the bare skin, they can become very dangerous, they can develop a rash/hair loss or ingest most of the insecticide percutaneously, which quickly leads to many complications, including death . I took the time to write this after seeing so many horror stories in the reviews here and then concluded that the active ingredient in this collar is the same as say the $50 collar, the only one The difference is how the drug is released. This is why it is so important not to over-tighten these collars.
