The U.S. Centers for Disease Control and Prevention says any animal suspected of being infected with the disease should be euthanized.
Tammy Kautzer of Dorchester says she doesn't want to kill the family pet, named Chuckles, but she says officials told her if she didn't the animal wouldn't be able to leave her property and everything on her farm would be quarantined until the pet dies.
Kautzer, her husband and their three-year-old daughter got sick with monkeypox after Kautzer bought two male prairie dogs in Wausau.
One of the prairie dogs died. Kautzer says Chuckles is doing well.
Wisconsin officials say 14 cases of monkeypox have been confirmed in the state and 25 more remain under investigation.
