Hill's

Hill’s Pet Nutrition is an American company that has been owned by Colgate-Palmolive since 1976. Its roots go back to 1948, when vet Dr Mark Morris Sr. arranged for the Hill Packing Company in Topeka, Kansas, to produce a food he had developed for a guide dog with kidney failure. That food became Prescription Diet k/d. Hill’s then launched Science Diet in 1968 as a wellness range for healthy pets, sold in the UK as Science Plan.

Choosing between them

Science Plan is the range for healthy pets. Pick by species, life stage and size, then by any particular need. The age bands are printed on the pack, which makes it easy to step up from Adult 1-6 to Mature Adult 7+.

Prescription Diet products are a different category: they are formulated to help manage specific medical conditions and are intended for use under veterinary guidance. Do not switch between Science Plan and Prescription Diet without speaking to your vet.
