Is there a warning to keep the dog away from cats for 24 hours after treatment with Advantage, as is found on Frontline?

Yes, there is a seperate and specific warning about not using it on cats and keeping dogs away from cats for 24 hrs. Highlited in yellow.

Is it ok to put advantix and advantage ii simultaneously on a larger dog? advantix for l and advantage ii for sm. that amount needed for bigger dog.

Each box will have a different expiration date on it. We had a box for at least a year, it still worked on the dog.

What are ingredients?

Strange that they leave this part out of the description as it is rather important. I have used this product on several dogs for years and purchased here and the online pet pharmacy out of Canada (wife ordered and I forget the name) but never had a problem but just like humans, some dogs have different reactions than others to certain products/chemicals, so do be careful to follow directions and monitor a bit to make sure your pet is taking it as expected and not having any reactions. Since they don't list it, I would email them seller directly, and/or look on the manufacturer website for more info.

what is the difference between Advantage 11 and Advantage?

Advantage II Is a better flea control and does not wash off as does Advantage. Advantage II is what you want!
