Fertilized Grass?

[hot fox]

We're moving house soon, the new garden has been treated with fertilizer and it's look unnaturally healthy and green! Compared to our current lawn which is frazzled and yellow and crunchy to walk on!
What I need to know is, how long until it may be safe to let the Piggles eat it? I don't think the product was anything particularly strong, but I don't want them to eat anything that could possibly be poisonous, as I'm sure they'd be some kind of weed killer in there. Do we cut it right back and wait until next year? There's lots of little frogs around too, so we're not sure what to do, we don't want to mow the lawn and end up with a Frog Massacre!
Any views on the safety of treated grass would be gratefully received, and on an aside, how do Frogs and Piggles react to each other?!

Oh dear, no idea on the frogs and pigs problem!

Usual advice that I've come across and as such tend to pass on is to wait at least until the grass has been cut three times, so roughly a month or so.

Yukkk!>>> Don't mow the frogs.
