Of course Heartgard is poison. It is an insecticide. The same goes for Interceptor. A lot of drugs are terrible for you in large amounts though. That doesn't mean it is safe to cut back without solid proof that it is okay (like studies from universities, etc.).

The Heartgard Plus chew cannot be cut in half because the drug is unevenly distributed and half of it may contain the whole dose and the other half, nothing.

I talked to Novartis and they said that I could not cut the Interceptor tab. I have no way if they just want me to buy extra or what but until I get more information, I would fell unsafe doing so.
