Mentioned on the guinea pig facebook group 
"Guinea Pig Ice Lollies - a *treat* to keep your guinea pigs cool this summer. Take some veg (not the type to wilt!) and/or some fruit (not too much!) such as cucumber, (gutted/seedless) baby tomatoes, bell pepper, or melon. Put in water and leave to freeze - remember to ensure it has melted just enough *BEFORE* giving it to your guinea pig as we don't want tongues stuck to ice! This does include sugary foods though, so watch the portions!"
