That's an interesting and practical question! Generally, standard residential or public space trash cans you buy at a hardware store don't typically come with a specific "warranty against animal damage." Most manufacturer warranties cover defects in materials or workmanship, but not damage from external forces like animals, weather, or vandalism.
However, the situation is different for heavy-duty commercial or municipal bins. Suppliers of high-end, wildlife-resistant containers (like those used in parks or bear country) often offer robust warranties. These might cover damage from attempts by animals like raccoons, bears, or dogs to break in. The warranty focus is on the durability of the locking mechanisms, reinforced materials, and structural integrity designed to withstand such attacks.
For public infrastructure, the responsibility often falls to the city or waste management provider. They may have service agreements that include repair or replacement of bins damaged by wildlife, considering it part of general maintenance. If you're managing a business or property, it's crucial to check the specific terms with your dumpster rental company or the manufacturer of specialized animal-proof bins. Investing in certified wildlife-resistant products is your best bet for long-term protection and potential warranty coverage.
