 And then the owners say, wow, you know, this is fine. And three months later call me and say, this product doesn't work. I have fleas. And then what they find is behind the sofa a stash of chewable products that the cat never ate. So if your cat's going to actually eat it and you're there watching your cat eat it, fine. The chewable products are just as efficacious. They work just as well as those spot-on products. It depends on your cat. And, again, that is also where your veterinarian comes into the picture to have a conversation.
