Princess Anne urges people to adopt abandoned horses The charity, of which the Princess Royal is president, has warned of an estimated 7,000 horses at risk of abandonment or neglect with the number coming into its four rescue and rehoming centres on the rise. "If you know what their physical limitations are, if there are any, if you know if they have any quirks, all of that is stuff that you don't normally get," she said. You can do a lot of awful lot good by taking a horse from rehoming, and I hope more people will at least find out what is involved because sometimes it may not be as difficult as they think. Animal welfare charities have warned that horses are being bred in large numbers in spite of a "saturated" market - leading to horses being sold at some markets for as little as £5. Hundreds of horses are being left in fields to fend for themselves, they have warned.
