Guinea pig · Life stages

Approximate age ranges for Guinea pig and the priorities of each stage.

  1. 1

    Juvenile

    Birth – 6 months

    Guinea pigs are born furry, eyes open and on the move; in their first months they grow fast and get used to their surroundings. Hay, sources of vitamin C and a guinea pig companion are the foundations of this stage.

  2. 2

    Adult

    6 months – 4 years

    Between 6 months and 4 years, a guinea pig's personality settles and daily routines are at their most rewarding. The right diet, plenty of space and regular care keep these years healthy.

  3. 3

    Senior

    4 years and older

    Guinea pigs are considered seniors from about 4 years of age, and many still enjoy happy years. Easy access, soft flooring, a calm routine and close monitoring make this stage more comfortable.

Age ranges are approximate; differences within a species (such as size in dogs) can shift the transitions earlier or later.
