Yes, it appears to be safe for dogs and cats. From the website: "It coats the lining of a part of the rodent’s lower gut. This coating of the “fine hairs” in the lower gut, called villi, disrupts the message system to the rodents brain causing it to stop drinking. This leads to dehydration, blood thickening, kidney dysfunction, coma and eventual death." I would still recommend that you place it in areas where your pets do not have access, and certainly not allow them to eat large quantities of this as it could cause vomiting and diarrhea.
