Made of hard plastic. Due to the "lock" mechanism to close the bait, I personally do not have it exposed in an area where my pet moves, although there may not be a problem. Of course, I expected it and for its price, it is very good.

So here we go! Supposedly, you buy a bait station with the belief that only rats and mice have access to it... 2 hours after it was placed, I see my cat approaching to smell it and immediately putting her paw inside, grabbing the bait with her claws, pulling it out and licking it! All of this happened within seconds and while I was about 40 meters away and happened to randomly witness the scene! Of course, I panicked and started looking for veterinarians to give me instructions! Simply unacceptable product. We got it to get rid of rodents... not our beloved pets!
