It’s empty in here!
This is used by all three cats and the best way of growing grass without having earth and mess everywhere. It is easy to keep clean and as they pull out grass it does not make a mess; the vermiculite growing medium is much cleaner than earth. I have two on the go, one sprouting every two weeks while they eat the grown one. it is easy to move around and keeps them healthy.
My boy is an indoor cat and does not have access to a garden. I buy grass and this grass planter is excellent as it refrains my boy from making a mess as he only has access to the grass and not the soil. I do recommend this planter.
