Typically guinea pigs are purchased as a first pet for children but it's advisable for parents to guide their children in the proper care of their pet in order to avoid certain stresses on the animal.

Compared to mice and hamsters, the average Guinea Pig, if healthy, can live from 5 to 7 years. This is a long time when considering the lifespan of other pet rodents like hamsters and mice, both of which have average lifespan of 2 or 3 years!


The University of Pennsylvania's Penn Veterinary Medicine reports the average lifespan of a Guinea Pig can be 5 to 7 years while the University of Michigan's Museum of Zoology reports guinea pigs can, under certain satisfactory conditions, live up to 14 years. (The Guinness Book of record's official record on a guinea pig's lifespan is 14 years and 10 and a half months.)

Breed Considerations

The species and breed of guinea pig you own is another factor to consider when gauging how long your pet will live. For instance, Hairless Guinea Pigs have an average lifespan of 7 to 8 years. This is a higher average when compared to the other guinea pig breeds and in contrast to the long haired variety which have a lesser lifespan; on the average of 5 to 6 years!

Diet Matters

Diet is another factor that can affect your guinea pigs lifespan. A well balanced diet can add years onto your pet's life. Guinea pigs are grazers and eat things like grass, herbs, dandelions and groundsel. For instance, it is recommended not feeding your guinea pig 'Alfalfa Hay' because of its high calcium count which can cause some health issues.

In place of Alfalfa Hay feed your guinea pig 'Timothy Hay' or 'Orchard Grass.' Guinea pigs also do not eat cereals, root vegetables or fruit.


Vitamin C is an important supplement for your guinea pig. Guinea pig grass based pellets make an excellent source of vitamin C as do green leafy vegetables such as kale. Guinea pigs cannot produce vitamin C. If the above foods are not available, then they must be fed supplements of vitamin C in order for them to remain healthy.

And please do not forget drinking water! Every living creature needs plenty of water in order to live and grow.

Health Conditions


There are a number of health conditions that can affect your guinea pig.

Health Problems affecting guinea pigs living alone are related to:

1) Aging.
2) Dental Diseases. (If your guinea pigs teeth grow too large, the little guy could suffer from an ailment known as 'tongue entrapment.')
3) Reproductive Disorders.
4) One condition facing your pet is called Bumble-foot.' This ailment is characterized by the ulceration of the feet.


For guinea pigs living together, infectious diseases from viruses and bacteria sometime occurs.

Infectious disease treatment can be tricky because guinea pigs are more sensitive to antibiotics than other pets.

All these conditions are conditions that can be overcome. If you ignore these ailments you could very well end up with a medical emergency that may shorten your guinea pig's life!

'Fly Strike'


When the weather is warm it is important to check your Guinea pig for 'fly strike." Check around the fur at the guinea pigs rear end for urine stains or stuck droppings which can attract flies. Flies can lay eggs there, which is often fatal for the guinea pig!

Other Considerations

There is no real perfect way to care for your guinea pig but some considerations should be made. Poorly ventilated, damp or a dirty environment could make a healthy guinea pig ill. So keep the area clean and warm but keep them out of extreme heat or extreme cold.


Less Stress More Life!

And lastly, as with many pets, keeping your guinea pig less stressed adds to their lifespan. Always be gentle and quiet around your guinea pig and never shout at or punish them. If they become nervous or scared they may display odd behavior like constantly hiding, cage bar chewing, over grooming, sitting hunched, immobility, or repeated enclosure circling. If this happens seek advice from an expert or contact your VET.
