Here Kitty, Kitty!

• For best results, grow cat grasses from seeds. We stock Botanical Interest Cat Grass. Choose a heavy, shallow container that your cats are unlikely to knock over and fill it about three quarters full with loose potting soil, using a spray bottle to dampen the soil as you add it. Place the container on a saucer or tray.
  
• Sprinkle seeds evenly over the surface. Cover lightly with about a quarter inch of soil.
  
• Cover the container very loosely with plastic wrap. Keep at room temperature and away from direct sunlight (and out of reach of curious pets). Make sure the soil doesn’t dry out.

• Sprouts should appear in a few days. Remove the covering and move the pot to a sunny spot.
  
• Water the sprouts when the soil begins to feel dry to the touch. Don’t let excess water sit in the container.
  
• Offer your cats the grass when it’s 3 to 4 inches tall. 

• When the grass wilts after a few weeks, pull out the shoots and plant more seeds. For a steady supply, plant several pots a week or two apart. Monitor your cats for signs of over consumption, such as vomiting or diarrhea, and limit access to the plants if necessary.
