[主題] Anybody heard of the oral treatment for fleas control?

I was introdued to this flea control treatment by the shop I usually buy my cat's supply from. The brand name is "Program" and is a monthly oral treatment. It comes in 6 plastic tubes with white liquid (133mg lufenuron each) in one box. I need to feed my cat one tube per month and it said on the box "the monthly oral treatment for the long term control of fleas, and the treatment of flea allergic dermatitis in small cats & kittens".
Anybody heard of this product? It's manufactured in France.
Sorry I don't have digital camera can't show you the box.

中文名是不是叫做 " 免洗蚤 " ???用吃的除蚤藥 , 之前好像有討論過 , 因為這種藥是阻止幼蟲孵化 , 對於環境或身上的跳蚤沒有殺滅能力 , 所以一段時間後就比較沒有人用了..........

我也有聽過用吃的…免洗蚤
不過它好像是日本做的，是一錠一錠的
其它的我就沒看過了!

yes ar, it prevents the flea to hatch but comes in plastic tubes
