Yeah mine too... I think the herbals work for us people a lot better and are more total body systemic but with the animals... they do not get enough and giving it to them is difficult... and of course the litter box etc..

anyway I found this, it mentions some chem dewormers.

I tried the one that he didn't like I am going to order some of the better stuff he recommends, like ProTal. it's a one dose, maybe once every couple weeks and then twice a year later thing, gets them out of the digestive tract/colon anyway, for the animals, and it's flavored so they like it. Shop around... I noticed the prices vary widely for different name brands and it's all the same stuff.
