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.
Frequently Asked Questions
Does this refill include the growing pot?
No. It contains seed and growing mulch for owners who already have the reusable MICHU Cat Grass Growing Kit.
Can I use the refill with ordinary potting soil?
It is designed for the MICHU soil-free growing system. For the most consistent result, use the refill with the MICHU container and follow the pack instructions.
How often should I replace cat grass?
Replace the crop when it becomes tired, mouldy, damaged, heavily chewed or develops an unusual smell. Growing conditions and usage vary between homes.
Why has my cat grass developed mould?
Excess moisture, poor airflow and warm conditions can encourage mould. Avoid overwatering, improve airflow and discard affected crops rather than offering them to your cat.
