The collar was totally ineffective for repelling ticks.

I tried the cat collar on my 2 cats. They hated it because it was a really strong smell, but I knew the oil smell would lessen in time. I kept it on them for about a month, but it really didn't do anything. The fleas were thicker under the collar than anywhere else on my poor cat.

We started our journey with Wondercide back in 2011 after our first little puppy developed severe gastrointestinal issues and then suffered a seizure after being administered a topical anti flea treatment.

I ordered one of these to try them out, although I have two dogs. I was having my yard sprayed by a professional company. What I’ve noticed is that the dog with the Wondercide collar has been left alone by mosquitoes and ticks, while the dog without the collar has mosquitoes swarming her and still has takes occasionally, despite the yard spraying. I will be ordering collars now for both of them.

I feel so much better with Wondercide flea collar on my Buddy.

My Dober girl Reign used to scratch incessantly so much, that she was getting cytopoint shots. I eventually realized that the scratching started whenever I applied Frontline. I decided to press my luck and search for a natural flea & tick repellent. I used Wondercide spray, but it was a pain as I sprayed her every time she went outside. I discovered the Wondercide Spot On. No ticks, no muss no fuss, but it needs to be applied monthly. Then, I noticed a Wondercide collar. It’s supposed to last 3 months! As soon as the spot on wears off, I’m putting the collar on her. All of the Wondercide products are great, and no ticks and no more scratching!

They looked good. Bought a 3 pack. Have two cats. But nice firm collar. But had them for a little over a month or so. Cats have fleas now. Was a nice idea to try natural. But does not work for my cats. Disappointing.

As of now I can't say they work or don't work for my issue is bigger than this. All my animals have one and all still have them. . .
