Food
As you can tell from reading the start of this page, guinea pigs like to eat. But what exactly do they eat? They are fussy little buggers and you will find that sometimes what one guinea pig likes doesn't neccessarily mean that all guinea pigs are going like it. Although I do know that the majority of guinea pigs like fresh grass. The best way to find out what your guinea pig likes is to try lots of different things. Some suggestions are: Carrots, Celery, Watermelon, Spinach, Lettuce (but not a lot... it can cause diarrhea), Honey dew melon, Strawberries, Broccoli and of course the guinea pig mixtures available commercially.
Try to give them a variety of foods because just like us they need it.
Bedding
Make sure they are warm and dry in their enclosure, Using straw / hay is good for their bedding and you might also see them eating it! Change the bedding regularly as they tend to make quite a mess where they sleep.
