My studio apartment was turning into a feline battlefield. My energetic tabby, Whiskers demanded vertical space, climbing surfaces, and a litter situation that didn’t scream “cramped chaos.”
As a fellow small-space dweller, I get the struggle of creating a functional, stylish home that doesn’t look like a cat tornado just rolled through.
I knew I was getting myself on a serious mission. And there are a lot of cat lovers who are in the same boat. I came up with the following 10 DIY cat litter box ideas that will keep your little furry friend happy while being space-friendly at the same time.
Bathroom DIY Cat Litter Box Ideas
Your bathroom can become a five-star restroom experience for your feline overlord. I’m talking about a DIY cat litter box that’s part secret agent, part interior design dream.
Start with an unused bathroom cabinet. Remove the bottom shelf, create a cut-out entrance for your cat, and line the interior with waterproof, easy-clean material.
Pro tip: use a dark-colored liner that hides… let’s say, “evidence” better than a light shade.
What You’ll Need:
- Old bathroom cabinet
- Jigsaw
- Waterproof liner
- Sandpaper
- Paint (optional, but recommended)
- Ventilation grate
- Measuring tape
The Process:
- Measure your cat (seriously, they hate tight spaces)
- Cut a smooth, rounded entrance
- Sand edges to prevent injuries
- Apply liner
- Add a small ventilation grate
- Optional: Paint to match your bathroom
The result? A concealed DIY cat litter box that looks like a chic bathroom fixture. Whiskers gets privacy, you get style. Win-win.
