4.  Entrants must ensure that their healthy adult cat is exclusively fed with Purina ONE dry and/or wet products. Changing a cat’s diet gradually by substituting a new food for old is ideal. This should take around 10 days; however, if the cat has a sensitive stomach, this time should be extended. The same applies when changing brands, even when keeping the cat on the same type of food (wet or dry). If the cat suffers from a medical condition or has specific nutritional requirements, consult a vet before changing their diet. To view the full Adult range visit www.purinaone.co.uk.
