Just talked to the vet's office. They are going to give me the Frontline Plus for large dogs and told me what dosage to use for the cats. Doing it that way is much more economical. For the cat version for 8 cats it would be $135 but doing it this way is just over $20...so that makes me happy. I feel so bad for the herd. Not only are they hot and miserable (it has been 90+ degrees this week in Pittsburgh) but they are itchy too...got a flea comb and have been using that on them, running the vacuum quite often (mostly hard wood floors, thank goodness!) and doing laundry quite often....

Wish us luck!
