The global market for pet products is worth $125bn of which pet food is 75pc. At the same time owners increasingly regard their pets as family members entitled to the best, which includes the freshly prepared, healthy food they increasingly provide for the human members of the family. Amazingly also, in the US, more households have pets than have children. It all adds up to a huge market opportunity for freshly prepared, refrigerated food for pets. Sales in the category grew 31pc in the US last year and one still-small but fast-growing company, Freshpet, is seizing the opportunity.
