Lauren’s Ollie?

I am looking after Ollie
He is my Grand daughters pet
Everytime I glance into his cage
Tis with torpedo poos I’m met

This animal isn’t very big
It is a guinea pig
But Wow can it eat, It never stops,
What the frig!!

The trouble is I give it food
After poop scoop it clean
Then I realise in five minutes
The ‘Shxx Machine’ has been

‘Crikey Moses’ you wouldn’t
Believe how much this pig can 
Feed
But then again it is well named
Every pig is know for greed?
