Make sure you're giving him some furball treatment, Betsy.
Whats that exactly ?
Well, cats eat grass for the same reasons that we would take a glass of alka saltzer. Grass eating can, but not always, be a sign that puss is building up a nice big furball he wants to shift. It can also mean wind, or he's eaten something dodgy. And some cats just like making themselves sick.
A drop of Defurrem covers you in case the cause is furball.
