My cat is an indoor-outdoor guy, and I check for biting critters on him every night. Since using Vectra (about a year, now) I have had to pull fewer ticks from him than ever . . .maybe 6 this summer. He has remained flea-less since I started; he doesn't run off when I dose him; there is virtually no odor. We are both happy! **Q: Are the ingredients the same for dog and cat?** A: I don't own a dog so I am not certain - but since Vectra makes a separate treatment for dogs I would assume they are not interchangeable. On the other hand, the actual ingredients may be the same or similar but I would guess the dosage differs, particularly since most of these products are designed to work by he weight of the animal. I do know hat at least one brand of flea treatment for dogs specifically says not for use on cats so I'm guessing the same applies to others including Vectra. **Q: does this medicine needs a prescription?** A: No, the entire Vectra line is categorized as a general use pesticide and is therefore regulated by the EPA, not the FDA. There are no EPA regulated products that require a prescription. **Q: What is the difference between the 'Green' version and the other one? The active ingredients are the same - which one to choose?** A: The "green" tube is for cats weighing more than nine pounds. I assume by "the other one" you mean the brown tube. As you noted the ingredients are exactly the same. It's the size of the dose that differs. The dose for larger cats is .041 fluid ounces per tube while the dosage for cats under 9 pounds is .027 per tube. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well *by E***A on December 31, 2025* This is a good product, works well on fleas and I have worked in several veterinary clinics where this product was sold, customers loved it. ### ⭐⭐⭐⭐⭐ Works great!! *by K***Y on November 5, 2025* After many failed attempts with other products, Vectra was successful at ridding my furbabies from fleas ### ⭐⭐⭐⭐⭐ It works for me, well tolerated. *by F***A on August 1, 2019* It works. Though my vet's office doesn't carry anymore. My cats get a little woozy and I make sure they stay indoors for 6-8 hours after applying. To be sure they aren't rain3d on as well as keeping an eye for any new effects. It's said not to be effective in my area any more. That is wrong. My 2 pets never have carried a flea into the house. I guess each area has its level of infestation. The problem is the OWNERS imo. And those 90 day products are so expensive and don't last 90 days and my pets had the-worst initial reaction of any I've tried, I felt bad giving that one to them. I'll stick w Vectra as long as I can. ## Frequently Bought Together - Vectra for Cats Flea Treatment & Prevention for Large Cats (Over 9 lbs.) 3-Month Supply - Vectra for Cats & Kittens Flea Treatment & Prevention for Small Cats (2-9 lbs.) 3-Month Supply - Vectra 3D for Dogs Flea, Tick & Mosquito Treatment & Prevention for Large Dogs (56 to 95 lbs) , 3 month supply --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/14929019-vectra-for-cats-flea-treatment-and-prevention-for-large-cats](https://www.desertcart.us/products/14929019-vectra-for-cats-flea-treatment-and-prevention-for-large-cats) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-23*
