Are worm castings the liquid worm poo? Is Poo here a verb or a noun? The liquid that worm poo or the liquid poo of worm? Sorry, but I'm so confused as usual. :D

"Compost worms or red tiger worms can also be added to a compost container and make worm ‘castings’ which is the liquid worm poo."

What does respect mean in this context?

"You will need to find red tiger worms in an existing compost bin, or buy them.

You will need to make sure you continuously feed them, because they are living creatures and need care and respect."
