I'm not all that surprised, I remember at one point when I was living in Ontario they were sort of at war with raccoons when trying to make a garbage container that prevented raccoons from getting in and was inexpensive enough.

At one point the lid was made more complicated so they wouldn't be able to open it...but this resulted in the material itself being somewhat cheaper, and raccoons would scratch the bottom of the containers until they made a hole to grab stuff out of.
