The youngsters, who have been named after Disney’s Frozen characters Princess Anna and Princess Elsa, were found in a poor state by the charity.
Elsa, a dark bay seven-week-old filly, was found next to her dead mother in a field in Redhill, Surrey, earlier this year (24 April).
Anna, a four-week-old skewbald filly, was discovered stuck in a big hole when she was less than a week old last month (15 May).
Anna joined Elsa at the RSPCA’s Millbook Animal Centre in Chobham, Surrey.
The foals are now being hand-reared and put on a lively display as they were let out into their new paddock together for the first time last Tuesday (2 June).
The foals were initially let out for an hour or two at a time to get them used to their new surroundings but are now enjoying full days in their paddock.
“We will continue to care for them until they are ready to be rehomed and hopefully live happily ever after.”
