Directions: How to apply the Seresto collar on your cat 1. Remove collar from packaging. 2. Unroll collar and remove the small plastic connectors from inside the collar, ensuring that no remnants remain. 3. Insert the end of the collar through the buckle and loops. 4. Adjust the collar around your cat's neck until it fits comfortably on them. 5. Two fingers should fit beneath the collar and neck to ensure it is not too tight. Any excess length of the collar beyond an inch past the loops should be cut off unless it is on a growing kitten, where some additional length may be needed for adjustment as the kitten grows. Also, make sure the collar cannot be pulled over the head. 6. Check periodically and adjust fit if necessary, especially if you have a kitten that is rapidly growing.

  • Safe
Size: 1 Pack
I have a munchkin Persian. She’s very little and this medication worked/is working well for her. I worry about chemicals and harmful irritants for her, but this is safe for her. I noticed a difference in a week after only bathing her once with dawn. No more scratching or fleas. It doesn’t smell, you easily clip it on and cut to the length you need if it’s too long. She hasn’t chewed or messed with it like her actual collar. I don’t think she knows she’s even wearing it. Great quality. The price is worth it don’t opt for the other cheaper products. ... show more

  • What a Good Investment This Was. It Works!!
Size: 1 Pack
I have to admit that I was skeptical of this product and the price point. I have a semi-feral cat likes to come inside during the day. He is not totally tame and doesn't like to be messed with a lot. To flea comb him is to risk being bitten (and he doesn't hesitate to bite). He was having a flea issue in the summer. I have had poor results from topical flea medicine in the past, so thought I would try this, because I didn't want a flea infestation in my house. Wow, he stopped scratching and the fleas disappeared from his fur very quickly after getting this product. He hasn't had any skin issues with the collar, his health is robust. If I could turn back time, I wish this would have been available LONG ago, I could have GLADLY used this product on some of my cats and dogs in years gone by. ... show more

  • TO DIE FOR...If you're a flea or tick.
Size: 1 Pack
I have purchased this for both dogs and cats for the past 6-7 years. They are a little pricey, up front. But they work for 8 months. They keep my pets free of fleas AND ticks! Other collars don't do this. I purchased one for a lady whose little dog was eat up with fleas. It was bloody where she had scratched and bitten at the fleas. She had spent over $100.00 in collars and shampoos. Nothing worked. Horrified, I purchase this collar for her. In less than 2 weeks she called me. The pup was flea free and the wounds scabbed over and healing nicely! No more scratching and crying! I love these collars... ... show more

  • Six months. Still working. Healthy cats. Yes, I will buy again.
Size: 1 Pack
I have four cats and Advantage had stopped working completely. The house and cats were hopping with fleas. It was horrible. I vacuumed. And flea combed. And used various products in the house short of fogging which is impractical when you have four cats living there. The vet's assistant had suggested these collars as an option. Came to Amazon because the price was much better and I needed multiple collars. Then I saw the reviews where people claimed their cats died and developed horrible skin reactions. That was a bit offputting. I hesitated. But the fleas were very bad and the vet's office--which I trust--had recommended them. I ordered three collars, figuring that I'd put them on my healthiest youngest kitties first (ages 11, 7 and 4--weights 10 to 16 pounds) first. My 14 year old cat (6 pounds) loves to be combed, so I would just comb her. When the collars arrived I, for perhaps the first time in my life, read the package insert that discussed the company's trials of the product. The only notable side effect observed in testing (as I recall it) was some dermatitis. It wasn't a lot of the trial participants but it was observed, and this explains the folks whose cats lost hair. Encouraged by the package insert, I put the collars on the cats. Initially, I was afraid that one of them was getting lethargic. Then I decided he had always been that lethargic and I was just paying more attention because I was afraid I was doing something that might kill my cats. Ultimately, the only effect these collars had was killing fleas. It took a couple of weeks because the fleas had gotten so bad, but they went away. About 99%. And the cool thing is, they also went away on my one cat on which I did not put a collar. Just having three collared flea killing machines wandering the house protects my fourth cat as well. She gets the occasional flea, but it's rare. And while I used to comb her twice a day to get the fleas off now I comb her once a week and find maybe one or two. Which seems pretty unavoidable given that she and two of the other cats go outside. It's been about six months now so the collars are supposed to last another couple of months. Hoping that by December there won't be fleas around to kill and that I can wait until spring for the next round of collars. Great product. Less expensive than Advantage for comparable months of effectiveness. And works like Advantage used to work when it was new. ... show more
