They gave me a total refund as stated on website I bought 2 collars for my 2 cats, and whilst waiting for their arrival I decided to dig deeper in to the safety of the ingredients (because I started hearing that essential oils were bad for cats). I read many different reviews from Amazon.com and Trustpilot about cats having bad reactions. Since my cats are indoor/outdoor cats I did not want to risk putting these collars on. So I emailed the company and explained my situation. Without any further conversations Dewelpro refunded all my money back. I am so pleased with the way they handled my situation. With whatever research I found on these collars, in my opinion, they seem to be safer for dogs than that for cats at any age

The best collar for my best friends I have been using Dewelpro for my 3 dogs for the last few years. I never worry about fleas, mosquitoes or ticks -and most of all I do not worry about putting toxic chemicals collars on my dogs. I only use them because they work and smell great too! Thank you dewelpro!

Got here fast Got here faster than I thought. I am rating the delivery right now as the flee & tick season has not started yet, so I can not rate the effectiveness of the collar itself.

Highly Satisfied Customer I first received one of these collars by accident. I put it on my dog and I was delighted by the results. No more scratched my and only 1 or 2 ticks the whole season. He was more comfortable immediately. This is important to me, also, because of Alpha Gal allergies. I love this product and plan to continue ordering. Thanks for a great job!

Thinner and cheaper made but cost more I ordered and received 2 collars. These collars are thinner and have a cheaper plastic clasp that I have to adjust the collars regularly as they get loose. We’ve been buying this type of collar every year for a few years now and this order resulted in a cheaper made collar that cost a lot more than our previous orders.
