I don't like to treat for fleas any more than I absolutely have to, and since not everyone has multiple pets, or has pets who go outside and need consistent flea treatment, I wanted to post this. When you buy topical flea treatments, they are usually sold in packs of at least 3-4 or more, which can get quite expensive. If you only need one treatment, rather than spending the extra money, and having the treatment sitting around and possibly expiring, what I do is go to my local feed store, and buy one treatment. I never knew there was a place that sold individual treatments, so over the years, I've wasted money on flea prevention that's sat unused, then expired, so I wanted to post this, in case it can save someone some money. Be sure to call your local feed store ahead of time, to make sure they have them in stock, and are willing to sell the treatments individually.
