Common questions

Is the rattlesnake plant the same as Calathea?

It was long sold as Calathea insignis and has been reclassified as Goeppertia insignis — either way, the whole group is considered pet-safe.

Why does my cat chew the leaves anyway?

Long, wavy leaves are fun to bat at. Occasional chewing is harmless; offer cat grass if the nibbling becomes constant.
