This is my time to shine, but I got here too late 😆 ages ago, my husband and I started using old ‘pub mix chip’ containers to store litter in. They’re large enough to hold a good volume of litter and light enough to easily pour

I’m linking below for reference but don’t buy these on Amazon, you will find them way cheaper at a grocery store or Costco
