With the vet's approval, Milo is going to become an indoor-outdoor cat starting a few weeks from now. So of course I'll be applying Frontline.
The local Petsmart wants $60 for Frontline or, rather, that's the price marked on an empty shelf. I expect I can do much better by ordering on line, but I don't want to have shipping charges eat into my savings, so I'm thinking of buying say a year's supply.

My question is, what kind of shelf life does it have? It would be a false economy to buy a year's worth and then find six months later that the stuff no longer works.
Please understand, I'm asking about shelf life. I know that once it's applied to the cat you're supposed to repeat it every month.

Stan,
I did some Googling and got answers from 1-2 years for an unopened container. IMO I would email or call the manufacturer just to confirm this. Would hate for you to spend a bunch of money for nothing.

Buy the Frontline made for large dogs, and use the DOSE for a you cat.

It's the same stuff, you just use less, and save a BUNCH of money.

By USDA law, ALL parmaceuticals are required to maintain 'full activity' for 6 months beyond their 'expiration date'.
I have used prescription medications that are more than 5 YEARS beyond their expiration, and it worked just as well as when it was new.

I did store it in my refrigerator.
I would recommend doing the same: buy the Frontline made for 'large dogs', and store it in your refrigerator.
Use it until it's gone.
Then buy more.

The shelf life of most medications can be greatly extended simply by keeping them in the refrigerator. Some can be frozen, but if not, just refridging them does wonders.

$60 for how many pipettes?
Used by date is often based not only on the contents but the packaging as well. Have you noticed even bottle of water have a used by date - of course this is referring to the plastic bottle that leaches chemicals slowly into the water.

I called Frontline once when I had some old stuff on hand. They told me it never expired.
