Guinea Pigs do love to cuddle, but they should get lots of exercise as well. They eat vegetables (no nuts or seeds) only, and they should get veggies daily. Guinea pigs need alfalfa or Timothy Hay (alfalfa has more fats) and pellets with vitamin c (vitamin c is crucial). They are very adorable; they will learn to recognize you, and squeal loudly for a treat. Mine recognize the word "treat", and they start wheeking away! For hygiene, chrissycat21 has already stated you need to clean their cage. They should also have a water bottle, but you can have a bowl instead. These bowls get really dirty full of pine shavings, etc. and a water bottle is better. Plus, if you get two, make sure they are the same gender, or you could end up with quite a lot of guinea pigs! Also, only two male guinea pigs that have known each other should be kept together, or if they just met, they can fight. I hope this info helps!
