Vital Stats of Little Critters

Most people are aware of the life expectancy, age of puberty and length of pregnancy for dogs and cats, but what about other types of popular pets? Guinea pigs, rats, gerbils, rabbits and hamsters are common pets, but vital statistics about these creatures aren't always readily available. Just how long will your small mammal live?

Life Expectancy

Age of Puberty

With such a short life span, many small mammals begin reproducing early in life. Knowing when puberty hits can help you prevent unwanted additional pets and to understand the reason behind a sudden change in behavior.

Heat Cycles

Once these little critters go through puberty, length of heat cycle is another important statistic to know.

Length of Pregnancy

If breeding is your intention, length of pregancy, also called gestation, can help you prepare for your little ones.

Size of the Litter
