I have an 8 month old kitten, who seems to constantly have worms? They go away for a little while when i treat them ( the sprinkle on the food stuff) but they return pretty quick :( . Unfortunately he is a bit of a hunter so constantly eating rabbits/mice/birds etc which i'm assuming this is where the worms are coming from? Can anyone recommend a really good wormer that will work some sort of magic on this poor boy? I cant keep him in to stop hunting, its too nice any sunny outside!
