If you have a cat, it definitely needs a litter box but how can you hide it to save your space design? There are some easy ways to do that, and the first one is to renovate some furniture piece – choose an IKEA piece of the proper size, make an entrance and put the kitty loo inside. In case you don’t want to use a furniture piece or don’t have one – just take a big wine box. A nice idea is also to build a self venting cat litter box in your own toilet but for this you’ll need to make a special tube inside. Read the tutorials below and choose the idea that suits you.
