I have 2 kitties, my boy is nearly 4 and my girl is almost 2. They both weigh about 10 lbs. We just moved into a new house that were renting. Before moving in, we thoroughly checked the whole house to be sure no mouse poison was in the house. We have been here for about 5 days and just found the second little blue pellet. From what I can tell from google images, it is mouse poison. I have no idea how it got onto the kitchen rug (both times) let alone where it is in the house. I didn't see either of my cats paying any attention to it either time, but I'm obviously freaking out!!!! I'm not sure what to do!! Help!!!
