M-PETS Grow Cat Grass, Indoor Growing Kit

M-PETS Grow Cat Grass is a growing kit rather than a tray of greenery: seed you plant and water on an indoor windowsill, so a cat that never goes out has something safe to chew.

Key Features

• Grow It Yourself: this is something to plant and water, not a pot that arrives green.
• It Is Grass, Not Catnip: the front of the box reads GROW CAT GRASS and nothing else. Catnip is a different plant and does an entirely different thing to a cat.
• What M-PETS Claim: a round seal on the front reading supports the digestion, with an asterisk, next to the word vitamins and a green tick. The small print behind that asterisk is not legible on the pack photograph.
• The Same Box In Orange: M-PETS sell GROW RODENT GRASS in the identical carton for rabbits, guinea pigs and hamsters.

Good To Know

• Cats eat greenery and then frequently bring it straight back up. That is ordinary behaviour, and it is the mechanism behind most of what gets promised for products like this - what comes up can bring swallowed hair with it.
• It is not a hairball remedy. A cat retching repeatedly, or straining and producing nothing, needs a vet rather than a windowsill.
• A pot on the floor is the cheapest way to stop a cat stripping your houseplants, and a great many houseplants are poisonous to cats. Lilies are the one that kills.
• Nothing grown keeps. Cut it down when it yellows and start the next pot; a mouldy tray is worse than an empty windowsill.
