Lambs at UK Wildlife Park Warmed by Knitted Jumpers From Anonymous Donor

— -- Newborn lambs at a U.K. wildlife park are staying warm thanks to the generosity of an anonymous knitter.

The Avon Valley Adventure and Wildlife Park in Bristol, England, says it received an anonymous package Monday filled with eight hand-knit jumpers for the park’s eight 2-week-old lambs.

“The jumpers were left outside the park with a note to say they were for the baby lambs,” the park’s marketing manager, Kim Pounsberry, told ABC News.

The lambs needed the extra warmth from the jumpers because they are orphans and it helps their survival, according to Pounsberry. Before the sweaters, the lambs had been wearing plastic “lambing jackets.”

Pounsberry said park officials believe the knitted jumpers came from someone locally but do not have any leads.

When asked what she would want to tell the donor, Pounsberry said, “A big thank you.”

“The lambs love them and they all look so sweet,” she said. “We’re always grateful for those who want to help us out.”
