After sharing the catio refresh in my previous post, I wanted to take a deeper look at the science behind the plants I chose. In honor of Earth Day, this post explores how cat-safe plants can serve as natural alternatives to synthetic pesticides while helping create a healthier space for both cats and humans.

From chaotic planter jungle to cozy balcony catio — the refresh begins. This small balcony catio makeover started as a simple refresh after a sudden California heatwave, but it quickly turned into a full troubleshooting project thanks to my two cats, Purrl and Jaspurr.
