How to build a grass bed for a cat?

[dreeped]

Hello!

I would like some idea on how I go about creating a bed of grass as seen the pictures below. Is there a shallow planter tray that exists in the store? Or should I look into building on my own. Recommendations for soil suitable for pets would be appreciated too. Thank you!

I've put this planter box together and noticed the base isn't solid for drainage purposes. There's a gap in the middle that runs the full length of the planter box and the edge isn't flushed. Should I consider sealing the base or add a waterproof liner? I'll need to reconsider a different drainage solution as I don't want the water to drip all over my balcony. Your suggestions would be appreciated. Note I will be chopping the legs down so the box is closer to the floor.

Hi @dreeped,

You could line the planter base and sides with GRUNT 2 x 5m Black 70um Multi Use Plastic Film to prevent it from leaking, but as you've mentioned, you would still need to find a way to handle the drainage.

Would some purposefully placed drainage holes with a saucer beneath be an option? You would need to leave some clearance when chopping down the legs, but this seems like the simplest option to me.

Let me know what you think.
