orchard

Is this 2nd cut orchard grass okay for them to eat every day? Is orchard grass the same thing as orchard hay? I know they can eat orchard hay but wanted to check.

Since I got my guinea pigs I have been feeding them Timothy hay. I recently bought a very small bale of oxbow orchard grass for a change and it was very popular. I like the Orchard grass as apparantly so I read it has a lower calcium content then most hays and its much softer then timothy...
