People on TikTok continue to impress with their innovative ideas, and one person just shared the transformative–and adorable–way they are using an old fish tank. 

TikTok user @mildwestsami posted a video showing their new use for a fish tank that she initially attempted to make a terrarium.

When that didn’t work out, she made the container into a “cat display case,” and now her pets take turns hanging out in the tank and showing off their cuteness.

The TikTok user explained the situation in a voice-over while the video showed the cats in the tank.
