Compare these minor drawbacks to the complications of a desperate dog or a rabid hamster, however, and you can see that you still clearly have a winning pet. Just Some Things to Bear in Mind Guinea pigs are herd animals originally found in Ecuador and Argentina. They have been bred in captivity for some time, however, and there are many different types of breeds available that are not even found in the wild. In the wild, guinea pigs generally follow the same route through their territory everyday, creating small but clear paths through the undergrowth. This tendency to establish set patterns is also manifested in domesticated breeds, which are more comfortable when following a stable feeding, exercise, and cleaning routine.
Guinea pigs are rodents just like mice and hamsters, so they have only four long teeth.
These teeth grow continually, so they need hard foods in their diets and may need to have their teeth filed by a vet. If you also provide them with chewing sticks or some other hard object to grind their teeth and claws on, however, a trip to the vet may not be necessary. Bear in mind that they need relatively large amounts of vitamin C in their daily diets, as guinea pigs cannot store this essential vitamin and are prone to their own peculiar type of scurvy. Vitamin drops are also available to put in their water if you don't want to worry about charting their daily intake.
