Guinea pigs are not pure bread rodents as they are more like hybrids. Ironically enough, they are not related to pigs; however, they do make certain pig-like sounds. They have a large head with a heavy neck, and the rear area is rounded with no tail. They are herbivores and eat mostly grass. They also eat their poop, especially caecal pellets that are needed to achieve complete digestion.
Unfortunately, these fun little animals only live to be four to five years old. Hamsters are also rodents, and they are stout-bodied animals. They are active during twilight, which is in the late afternoon and early evening, and then they close their eyes and take a snooze.
They do well eating prepackaged hamster food, which is assorted fruits, vegetables, nuts, and seeds. They have pouches on either side of their head, which they use to store food for later. Unfortunately, hamsters have a shorter life span than the guinea pig. They only live for one or two years.
