Capstar (nitenpyram) Cat Flea Treatment, Fast-Acting Oral Flea Treatment for Cats 2-25 lbs, Vet-Recommended Medication Tablets Start Killing in 30 Minutes, 6 Doses

Amazing stuff ! Immediate action, dead fleas start falling out of our cat's dense coat in 30 minutes or less. Seems to take up to maybe 4 hours to completely kill ALL the fleas ! This tablet makes every other fleas remedy a joke. It doesn't stick around for long, or work for long though. It just kills fleas right away, then it's eliminated from the cat's system within hours. VERY VERY EFFECTIVE !!! It seems crazy that it can be used every couple of days, or on mother cats feeding kittens. Evidently it works by interference with an enzyme involved in making fleas shell exoskeleton bodies. Mamals don't have or use that enzyme I guess, so there's no effect on the cat ! But it kills fleas really quickly ! It's gratifying to see them falling out of his fur... Be aware that the fleas might be trying for a last meal or jumping around as they die. Something makes our cat a *litt bit* crazy going after fleas for an hour or so after taking Capstar. Nothing major, but you might notice it. It doesn't last long at all because all the fleas DIE quickly ! No fuss, no muss, just a comfortable cat in 2 hours or less in my experience ! It's PAINFULLY EXPENSIVE, but it works extremely well, and it's a lot less time, mess, and chemicals than an effective flea bath.

My two indoor cats somehow acquired fleas. I had no idea until the scratching became impossible to ignore and a flea comb confirmed my nightmare. I ordered Capstar immediately, and the results were fast enough to be genuinely startling. Within 30 minutes of getting the tablet into both cats (hidden in a spoonful of wet food, worked perfectly), they were doing what I can only describe as the flea awareness shuffle: slightly agitated, moving around, giving me confused looks. This is normal and brief. What followed was watching dead and dying fleas surface and fall off the fur over the next hour. It is equal parts gross and deeply satisfying. One tablet kills over 90% of adult fleas within six hours of administration. That is not marketing language, it is accurate to my experience. The relief was visible and immediate. Important context every buyer should have: Capstar only kills adult fleas currently on the animal. It does not kill eggs, larvae, or prevent reinfestation. Each dose lasts approximately 24 hours. For a full flea protocol, you will want to pair it with a monthly preventative and treat your home environment as well. Think of Capstar as the emergency first strike, not the complete solution. Tablets can be given as often as once daily during an active infestation, which is genuinely useful. Administration is easy once you figure out your cat's preferred method of deception, whether that is wet food, cat broth, or a pill popper. The six-dose pack gives you enough for a meaningful treatment window. Highly effective for what it does, and vet-recommended. Keep it in the cabinet before you need it.

Works well to kill fleas fast, but… The Capstar starts working within 30mins, and kills all biting adults within 6hrs and leaves the cats system after 24hrs. It does not target the larvae and eggs, and the cycle will continue. You will need a longer lasting topical along side the capstar to “target” the larvae and eggs. I got frontline plus as my part 2, it doesn’t kill larvae and eggs either, it just stunts their development to maturation they will naturally die off of starvation within 1-2weeks. The cocooned pupae can still be protected and dormant for 6-12 months if undisturbed. It does what it says - but NEEDS part 2 + Steam cleaning and daily vacuuming.

Very impressed so far. My six year old cat recently got fleas for the first time ever and the topical treatment we were using wasn’t working. I was a little skeptical about how my cat would take meds orally, but it was no problem at all. We just broke it up and mixed it in with his wet food. I was shocked at how quickly they started working. Within an hour, my cat was going crazy because all of the fleas were moving everywhere (which means it’s working). We went out to dinner and came back, and there was at least fifteen dead fleas on his blanket outside. I’ve never seen flea meds work that fast. And I also like that if you aren’t sure if your cat kept the pill down, it is gentle enough to give him one each day.

They are bitter, I coat it butter or sour cream. But they are small and very hard so if they spit it out you can keep trying. They kill most of the fleas. Expect your cat to act like the fleas are driving them crazy at first, it means the fleas are reacting. They die off pretty quick. It's not long lasting, you still need to use a topical and de-flea your cats environment.

It took us forever to get rid of fleas. There was no sight of any except on the cat. We used nearly all of these to finally get somewhere with killing them. I wouldn’t wish fleas on my worst enemy. I mean this is the first step to killing the ones on her then you gotta clean the mess off the cat and the surroundings. Ugh. PTSD while writing this now that they’re gone. She scratched, she spazzed, she was all over the place after we gave her a CapStar cuz they’re moving around her more freaking out - that’s normal. They’re super small so easy to hide in her food so she’ll eat it.

Amazing how well this pill works at eradicating fleas on your cat. Our outside cats had spent too much indoor time and spread their angry fleas to our indoor cat as she enjoys playing with them when they come in. We treated the rugs with flea powder, bathed our indoor cat and gave her a single pill, the next day ALL the fleas were DEAD AND GONE. We did notice that she threw up her dinner a couple hours after taking the pill so it seems she did have a slight negative reaction. It's been several weeks, she's had no further reactions and the fleas have not come back. We have kept her inside and attempt to keep the outside cats from running inside everytime you open a door. Hearding cats is a lot of sun. This pill works and it works FAST.
