Our take
Hill's is one of the big vet-recommended brands, and this is its bread-and-butter indoor formula. It is built for cats that do not roam: controlled calories to hold a healthy weight, a fibre blend to help move swallowed hair through rather than into hairballs, and ingredients aimed at firmer, less smelly stools. It is not a boutique recipe, but it is consistent, feeding-trial backed and easy to find, which is what most house cats actually need.
