Great Results for One Year!
Size: Over 9 lbs, 6 Dose
I've been using the Advecta topical flea treatment on my two cats (10lbs and 22lbs) for one year, and it's very effective. It's easy to apply once a month, and I personally prefer a topical treatment over pills or collars. My cats are indoor/outdoor, and have never had an issue with fleas while using this product consistently. I used a much more expensive brand previously, and this works just as well at a better price. The main thing is to be consistent with the application each month. If you do that, it's been an effective and reliable treatment for my cats. If you're looking for a cheaper alternative to the more expensive treatments for your cats, I'd highly recommend this one! ... show more

Works really well !
Size: Over 9 lbs, 6 Dose
Arrived quickly, I have used advecta for the past few years, it works pretty well, doesn't seem to bother my cats. Comes in a 6 pack ( I have 6 cats, 3 indoor, 3 outdoor) at a reasonable price.

Works but takes longer to see results than advised.

This is a good product. I have thick coated cats & always wish it was much stronger because the hair absorbed the drops .

Did not fix my cats’ flea problem at all.
Size: Over 9 lbs, 6 Dose
I bought this treatment for adult cats, but it completely failed to work. I followed the instructions perfectly and applied the treatment multiple times over a two-month period, but my cat still has fleas. This product is completely ineffective, and I threw my money away. I am very disappointed with the results and I absolutely do not recommend it to anyone. I guess you get what you pay for. ... show more
