Dog food, cat food, treats and litter are pricey at full RRP, and pets eat through them fast. We compare Whiskas, Felix, Pedigree, Bakers, Dreamies, Sheba and own-brand ranges daily, so the biggest drops on your pet’s usual food show up first. Today’s deals in this aisle are at Tesco, Sainsbury’s, ASDA, Morrisons, Waitrose, B&M and Ocado.
