http://www.animalmedicationdirect.co.uk/protexin-pro-fibre-small-animals-800g-c-5-p-5-pr-5682.htmlI am crusing the net looking for one supplyer for ivermectin, fibreplex, panacur and frontline (frontline for the cat dont panic) when I found this. Has anyone used it, is it like critical care or more like a supliment to add to food/water ?
