Fleas, ticks and worms are common parasites in cats but they can be easily prevented with regular treatments. Fleas are extremely irritating and in some cases can lead to skin disease. Worms can result in gastrointestinal problems in cats, which includes diarrhoea and vomiting.
Typically most flea treatments should be applied each month and come as a spot-on solution which is easy and simple to apply. The rate at which you should worm your cats depends on their lifestyle, hunting cats should be wormed monthly as they are at a great risk of getting a worm burden, otherwise it is advised to worm your cats every 3 months.
