How to Use the Refill

1. Empty and clean the reusable MICHU growing container after the previous crop.

4. Water as directed without leaving the growing material waterlogged.

Cat Grass Safety and Care

Cat grass is optional enrichment, not a complete food or a veterinary treatment. Supervise access, remove any mouldy or damaged crop, and replace grass that smells unusual or becomes heavily chewed. Contact your veterinarian if your cat vomits repeatedly, shows digestive discomfort or consumes unusual amounts of grass or growing material.
