Liza Michna, 37, of Racine said she was at the hospital with her daughter, who was in a diabetic coma, about two weeks ago and returned home to find one of the lion statues that used to guard her front door was missing, The (Racine) Journal Times reported Monday.
Michna said the second lion was taken two days later and replaced with a lawn gnome.
Michna said the lions were a gift from her husband and five children on Mother's Day last year.
"I love those things," she said.
Michna said she won't press charges against the pranksters if the lions are returned unharmed.
"They can have their gnome," she said.
