TevraPet FirstAct Plus Flea and Tick Topical for Cats over 1.5lbs, 3 Dose Waterproof Flea and Tick Control/Prevention for 3 Months

I’ve been trying out the TevraPet FirstAct Plus Flea and Tick Prevention for Cats (Over 1.5lbs, 6 Monthly Doses) on my two cats, and it’s been a bit of a mixed bag. If you’re looking for an affordable alternative to big-name flea treatments, this one’s worth considering, but it comes with some caveats.The Good Stuff: This topical treatment uses fipronil (9.8%) and (S)-methoprene (11.8%), the same active ingredients as Frontline Plus, which is a major plus for budget-conscious pet owners. The 6-dose pack, priced around $25-$35, offers a full six months of protection, making it way cheaper than name brands. Applying it is straightforward—part the fur at the base of your cat’s neck, squeeze the applicator onto the skin, and you’re done. It’s waterproof, so baths or rain won’t wash it off, and it’s designed to kill fleas, flea eggs, larvae, ticks (including Lyme disease carriers), and chewing lice for up to 30 days per dose. My indoor cat hasn’t shown any fleas since I started using it, and several Amazon reviews echo this, with one user saying it “worked as well as Frontline for a fraction of the cost” and kept their outdoor cat flea-free. It’s made in Germany in an EU-GMP certified facility, which adds some reassurance about quality control. The fact that it’s safe for cats over 1.5 lbs and 8 weeks old makes it versatile for most feline households.What’s Not So Great: Here’s where things get tricky. While some users, including myself, have had success, others report it’s hit-or-miss. A few Amazon reviews were brutal, with one user claiming their cats had “the worst flea infestation ever” after using it, even when paired with oral treatments like Capstar. Another mentioned skin irritation on their cats’ necks, which I haven’t seen with mine but is concerning, especially for cats with sensitive skin or flea allergies. The applicator’s sharp edges are another issue—one reviewer warned it could scrape a cat’s skin if you’re not careful, which is a design flaw compared to smoother applicators like Frontline’s. Also, if your cat has a heavy flea problem or you’re in a high-infestation area, you might need to apply it every 30 days (or even more frequently for flea allergy dermatitis), and results can vary. I’ve noticed my outdoor cat still scratches occasionally, so I’m supplementing with regular grooming. Lastly, it’s not for dogs, so if you have a mixed pet household, you’ll need a separate product.Final Thoughts: The TevraPet FirstAct Plus is a solid budget option for flea and tick prevention, especially if your cat’s infestation isn’t severe or you’re using it preventatively. The price and vet-quality ingredients make it appealing, and it’s worked well for my indoor cat. However, the mixed reviews on effectiveness and potential for skin irritation mean it’s not a guaranteed win for every cat. I’d rate it a 3.5/5—great value and easy to use, but the inconsistent results and applicator design hold it back. If you’re trying it, start with the 3-dose pack to test it out, keep an eye on your cat for irritation, and pair it with good grooming and home treatment for best results. It’s a decent alternative to Frontline, but don’t expect miracles in heavy flea zones.

Did not seem to work right away…but no fleas a week after applying so it may be working well enough.
