A New Milford, who once ran a dog rescue operation, pleaded guilty to endangering her three sons and forcing them to stay in dog cages.
Robbin D'Urso, 49, of New Milford, was arrested in September 2009 after her 14-year-old son complained that his mother had abused him and his two younger brothers, then 12 and 10.
She pleaded guilty on Wednesday to three counts of reckless endangerment and faces up to three years in prison when she is sentenced next month.
D'Urso once rescued abused dogs and pleaded guilty to animal cruelty charges and was placed on probation in 2006 after police found 130 caged dogs at her then-Fairfield home.
She was arrested in 2007, accused of violating terms of her probation that she was not allowed to have dogs at her home, the Connecticut Post reports.
She was fined but allowed to remain on probation.
Three months later, an associate of D'Urso's so-called animal rescue operation was reportedly seen by a probation officer in the garage of her home with two dogs. D'Urso was then sentenced to 60 days in prison, the paper reports.
