I'm confused then because the site Purina - says:
"Felix, the nation's favourite black and white cat, is a cheeky rascal - just like your cat! He also demands the tastiest food - which is of course Felix! First launched in the UK in the 1970’s, Felix is a nutritionally complete lifestage cat food that comes in a huge range of textures and tastes, including delicious cans, tasty trays and tempting pouches, as well as crunchy dry complete. There are special varieties available for kittens and senior cats, along with tempting treats and milk. With its irresistible taste and fabulous range of flavours it's hardly surprising that cats like Felix, like Felix!"
