The other day while walking through Costco on the way to the cat litter, I saw they now have their own brand of a spot on flea medicine. Since I've usually been pleased with Costco brand products, I took notice. It's called Kirkland Signature Flea & Tick Control for Cats. It was less than $20 for 6 applications, I figured it can't be any more toxic than Frontline or Advantage right? WRONG.
Well, before opening the package, I thought I might do a quick search for reviews of the product and boy am I glad I did, wow! First thing that came up was Amazon.
26 reviews and 24 were extremely negative. People reported their cats had all sorts of extreme reactions to the product. Many needed emergency vet care as their cats experienced severe burns, seizures, lethargy, lost appetite, difficulties breathing, the list goes on. The reviews read like a list of horror stories.
Next up on the review list was Advantix vs. Frontline. They compared the ingredients on the Kirkland product and found the listed ingredients to be the same as Bio Defense Spot On. They looked up reviews on Bio Defense and found mostly negative ones. A few people shared their experiences of the Kirkland product at Advantix vs. Frontline and they were also heart wrenching.
I thought I might look over the packaging a little more thoroughly after finding all this out. What I found disturbed me even more. Here is the back of the package. (If you want to read it, click on the picture to make it bigger.)
The parts that were most alarming to me was first the WARRANTY AND CONDITIONS OF SALE section, especially the last two sentences.
The little yellow box was also alarming.
Seeing all this information and bad reviews made me wonder about my trusty Advantage II for Cats by Bayer. On the back of the Advantage II there are no warnings about reported side effects only the statement, "Individual sensitivities, while rare, may occur after using ANY pesticide product for cats. If signs persist, or become more severe, consult a veterinarian immediately." There is no warranty or conditions of sale listed on the outside of the package, however on the leaflet inside the box there is a similar limited warranty and limitation of damages statement.
Lastly, I looked at Amazon to see what the reviews were of Advantage II for Cats, and they were about the opposite of the Kirkland product.
