I just saw a blurb about something similar in the US! Mars (the candy company) is 'the largest owner of stand-alone veterinary clinics in the United States.' Also: 'JAB Holding Company, the owner of National Veterinary Associates’ 1,000-plus hospitals (not to mention Panera and Espresso House), also holds multiple pet-insurance lines in its portfolio.'
