WORMING Regular worming is vital for cats and kittens - a kittens first wormers should be given by their breeder before you collect him/her. Thereafter they should be wormed at least every three months, especially if you have children or are regularly visited by children. Once every month a "spot on" can be given to protect your kitten/cat from round worm as well as fleas, ear mites and lung worm. Its coming to that time of year when there will be flies around, they can bring worm eggs, as well as bacteria, and other internal parasites onto our cats food. Worming is required even if your cat doesn't go outside. Your footwear can also bring in unwanted parasites into your home that you cat can pick up.
