So, here’s a cat food containing anti-hairball complex, micro-fibres and psyllium to break down swallowed cat hairs or pass them through the body in a stool, while at the same time it appeals to your cat’s instinctive food needs and tastes. This is pretty awesome, especially when you take into account that a cat spends 30% of his day working his coat with his rough tongue to get rid of dead particles and loose hair and that two-thirds of these hairs end up in the stomach. An effective hairball fighter is just what your cat (and you!) need. Don’t be such a sceptic, more than 40 years of scientific research has proven the effectiveness of Royal Canin’s hairball expulsion plan.
