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.

I've tried other cat grass

"I've tried other cat grass seed, but nothing g compares to Michu. It germinates and grows real fast and gives my cat some lush green grass to nibble on. Plus it stays green much longer than other grass. Which is why I reordered it in the first place. I'm very pleased with it. 😘"

My cat enjoys the Michu

"My cat enjoys the Michu grass that grows inside in a dish. She likes the green grass and it does not make her throw up as she does eating grass growing outside! “The Cat Ladies” provided me with a calico cat container that looks just like my Blessi, who is also a calico! 😻"

My baby girl LOVES these.

"My baby girl LOVES these. While these were back ordered, we bought the grass from Petco. First - they brought what looked like fruit flies into the house. Second, she wasn’t a fan at all & it smelled stagnant. I have since ordered a boat load of seeds so she never has to go without. All out there with cats - you know the judgement! lol"
