Can Guinea Pigs Go On Mowed Lawn?

[luckyandsammy]

My dad mowed the lawn this morning and I'm not sure if the piggies can go on it?
The lawn mower uses petrol and I don't want the left over fumes to hurt them(if there is any?)
How soon can they go on it?

As long as the grass clippings have been cleared away then they can go on it straight away.

Thank you!
There is a basket at the back of the lawn mower that catches all the clippings.
I didn't put them out this evening because I was worried about them getting poisoned and I felt a bit bad because the weather was nice but they were out in the morning before the grass was cut so they are okay

I will put them out tomorrow morning
