The nice thing about this design is you can put caps on at night.We've been fighting rats galore this year; warm winter + COVID-19 shut down meant closed restaurants = no regular food source, everyone has chickens and veg gardens, and the demolition of an abandoned industrial site nearby, just disgusting infestations everywhere. I can only use metal cans to store food in but I need something like this badly. I'm going to try this with a small metal garbage pail with a gasket to see if it will work.
Then on to a winter-proof waterer.![]()
However, rats are pretty strong and can be quite determined.... I wonder if it would be better if you found threaded pipes so that you could use a screw on cap...
