See your cat munching grass? It's not weird - it's instinct. Indoor cats especially benefit from a constant supply of safe, homegrown grass. It aids digestion, relieves boredom and gives them a taste of the outdoors.
Why cats eat grass
- Digestion: grass fiber helps move hairballs and indigestible bits through
- Natural behavior: wild cats eat grass regularly
- Entertainment: it's a sensory treat that relieves boredom
- Possible nutrient supplement: grass contains folic acid and vitamins
How to grow cat grass
- Buy wheatgrass, oat or barley seeds (all safe and cat-approved)
- Soak seeds in water overnight
- Plant in shallow soil or a soilless grower, lightly covered
- Water daily and keep in a sunny windowsill
- Harvest when grass is 10-15 cm tall - offer to your cat
- Replant every couple of weeks for a constant supply
⚠️ NOT the lawn grass
Outdoor grass may carry pesticides, fertilizers or parasite eggs. And lilies, which cats love to nibble, are FATALLY toxic. Always grow indoor cat grass from safe seeds.
🐾 Keep it fresh
Once grass starts yellowing, compost it and start again - stale, rotting grass loses its appeal and can upset tummies.
A pot of fresh grass is a tiny, cheap project with outsized benefits. Your cat gets enrichment, better digestion and a daily "outdoor" snack - no garden needed.
