What is Reddit's opinion of Advantage II Flea Prevention and Treatment for Large Cats (Over 9 Pounds), 6 Pack?

From 3.5 billion Reddit comments

I know of one solution to completely getting rid of them. I have 4 cats and even though they're indoor cats they had fleas. My wife bought "Bayer Advantage II Flea Control Treatment for Cats" from Amazon, we put it on the back of their necks, and it worked immediately getting the fleas off of them.

As far as getting rid of them (or any other similar insect, including bed bugs) in your house, diatomaceous earth is a great solution since it's a completely natural substance that contains no chemicals and isn't harmful to humans or animals. Diatomaceous earth has razor sharp edges at a microscopic level that gets into the exoskeletons of small insects like fleas and bed bugs which cuts them and dries them out... eventually killing them.

I restore furniture as a hobby and accidentally introduced bed bugs into my house. Pest control quoted us at $200 a room. I put the diatomaceous earth in one of these dusting bottles and coated my entire house. It made quite the mess from all the white powder but it worked immediately and I haven't had problems since... except occasionally cleaning up the excess dust that I sometimes find behind the furniture.

Advantage 2 for cats over 9 pounds (there is also 5-9 pounds and kittens, so get the right one).
