Allergic reaction in cat and terrible customer service Put collar on cat and within 10 hours her neck swelled up. Contacted customer service. They challenged me and didn’t believe me. No care for the animal expresses. Finally after sending before and after shots(she hassled me also about pic qualities…it is hard to get a good pic of a stressed cat with swollen neck) she offered to refund me one collar. I had purchased 3 collars to stock up given their website mentioned no expiry if stored properly.

Great Natural Solution These flea/tick collars are natural and safe. We have used them for 3 years and prefer over more dangerous chemical flea and tick techniques. These are 25 inches in circumference and fit our 70 pound dog well. They arrived on time. These were a bit too pricey and used to cost much less.

Love your collars! Love your collars!! No pesticides are great for my pup!!

Didn't work as I expected Soon as I put it on my cat he started running around crying I mean he didn't like it at all I thought that was it working and had the flees going crazy So I didn't worry much so after a few days I noticed he had been scratching it around his neck to the point his fur was gone in that area and it was raw wet skin I had to take him to the vet cost me $100 for the ointment

Dewell flea collars are the best.... I ordered 3 Dewell flea collars to replace the Seresto collars my cats already had on for 8 months. I decided to try them because they had excellent reviews and were made with essential oils and not chemicals like the other ones. One of my cats has very sensitive skin and was continually scratching in spite of the previous collar. I had to use the flea collars because he couldn't tolerate any flea medication applied directly to his skin. I can honestly say his skin is clearing up and he is no longer scratching. Also...the collars smell wonderful!! If they made a fragrance that smelled like that I would buy it! Lol! If you are considering buying the Dewell flea collar I would strongly encourage you to do so. I'm certainly glad I did. From now on it's only Dewell collars for my kitties! And they're less than half the price of Seresto collars!!
