Just recently, for the first time, I used Drontal wormer for my cats. This was an unpleasant experience for both the cat and myself; having to try and force a table down the poor animals throat.

I have always used Panacur and had excellent results, and I have never had to fight with the animal.

I find if you have a pet that doesn't like the wormer in their mouth, then just mix it in some food, unlike a tablet that they seem to find every time.
