I use panacur liquid to worm my kittens,and drontal tablets for the older cats,as trying to syringe 3 lots down doesnt go down well frontline combo is good(only available from vets)as it prevents fleas breeding in the housei wouldnt bother buying frontline from pet shops etc as ive been told its been made weaker since its been released to pets shops to sell! dont bother with super market brands like bob martin/sherleys as its a load of c***!also feeding a quality dry diet such as science plan/hills,nutro,royal canin,orijen,its more expensive to buy,than super market brands but they will eat less,poo less,and benefit from it.And dont forget the scratching post!
