My daughter had two young healthy fancy rats. Their names were Peaches and Princess. As everyone knows rats are fun loving animals, however can be very stinky. I bought the Hartz bedding spray for small animals. I sprayed it in their cages after changing the bedding. I then put the rats back into their cage. The next morning both of them were dead. My daughter is heart broken as well as the rest of our family. I will never use a Hartz product again. Shame Shame on these people for selling products that kill!!!
