Really? My girls would be stuffing their faces if it was warm enough. We don't talk about busy bees around here - our proverb is "as busy as a guinea pig on grass".
To be honest it took my lot a while to get the point of lawn time too.
Stick with it - he will work it out eventually!
And I am so envious of your grass.
We have gorgeous sunshine here, but the lawn looks very sad after being under snow for months.
I think we have a while before our piggies set foot back out on the lawn.
Gorgeous Spud
My pigs (and me!) very jealous too, looked like my grass was recovering then the new couple I share a garden with keep letting their dog do it's business everywhere! Grr!
