Litter box mess problem fixed!

I have 2 cats. Padme my eldest is 3 years old and our new arrival Sheba is 8 months old. We got Sheba from the ASPCA 3 months ago.

DIY cat litter box

She is a funny girl and moves around quite a bit. She gigs in her litter box like it is a life and death matter and spreads all the litter box outside of the box. Which brought litter dust all over the apartment. I bought a storage box at Bed Bath and Beyond which fixed the problem. It is from Iris and has a winged lid. I leave one open for access and opens both to remove daily waste. Since then I buy less litter and my apartment is almost litter free.
