Zhu Zhu Pets Hamsters are the must-have gifts of this holiday season – and now they may not be safe for your health. 
ST. LOUIS – A consumer group contends one of the holiday season’s must-have toys is unsafe.
San Francisco-based GoodGuide named the furry robotic Zhu Zhu Pets hamsters Saturday as one of the top-selling toys with low ratings.
It says it found a higher-than-allowed level of a chemical called antimony, which can cause health problems.
The group assigned the toy a rating of 5.2 on a 10-point scale.
The toy’s maker, St. Louis-based Cepia LLC, insists in a statement that its product is safe and has passed rigorous testing.
