I currently live in florida (enough said)So I've had stryker on frontline and heartgaurd he also gets a flea shampoo bath once a week, but lately we've had stray cats running through the yard and it appears they're bringing more of their little friends. I picked 4 or 5 fleas off him last night, I looked through past threads and sentinel was recommended but when I went to go purchase it there currently is a halt in production so is there another alternative that works as well for heartworm and fleas?
