Royal Canin Intense Hairball 34 helps minimise the forming of hairballs in sensitive cats. Intense Hairball 34 is designed for cats that are subject to hairballs like semi-longhaired cats. Intense Hairball 34 has balanced nutrients which nourish your cats coat to keep it beautiful and regenerated. With a supply of psyllium Intense Hairball 34 stimulates your cats intestinal transit to flush out hair that has been swallowed through the faeces rather than forming a hairball in the stomach and your cat regurgitating.
