Do the seeds or roots underneath hurt the pigs? I, too, have just found that my piggies LOVE the "pet grass" or "wheatgrass" you find in the produce stores. I also heard that it's insanely healthy for them. I keep cutting it, worried that they'll eat the seeds underneath and also wondering how to keep the stuff growing. ???
A wheat grass tray like this sounds like a great project for my son and I to do together. My piggy will be ecstatic! Spring seems like it's a long time coming...
