At Family Pet Veterinary Practice (FPVP), we have a special interest in seeing rabbits, guinea pigs, chinchillas, rats, hamsters, and other rodents, as well as the odd ferret, hedgehog, or sugar glider.  We know that big hearts and personalities can come in small packages, and the value of a pet should have nothing to do with purchase price!

One of the more frequent “exotic” small mammal pets we see is the guinea pig, so we will focus our first blog post on this adorable animal.

Guinea Pigs as Pets

Guinea Pigs make good pets, and are a good first choice for teaching pet care to children.  They are gentle and interactive, and easy to keep in the home.  They love to eat, and some will squeal and chatter excitedly before meals!  If scared, they tend to freeze or run for cover.  If housed, fed, and cared for properly, they rarely get sick.  Their life span averages 5-6 years, with some living to 8.

Housing

We recommend using cages with a solid bottom (wire mesh can cause foot injuries).  They do not need a top if the walls are 10” tall or more, since they are unable to jump or climb very high.  A guinea pig should have a minimum of 7.5 square feet of space, but the more room they have the happier and healthier they will be.  Use the following link for more specifics and some great pictures of cage setups:   https://www.guineapigcages.com/

The substrate of the cage can be either wood chips (although avoid oil-containing products like cedar and pine) or paper (store bought paper pellets, or shredded newspaper).  Guinea pigs should have a shelter for privacy.  These are commonly store-bought huts, igloos, or tubes.  Cardboard boxes can be used, but as the pigs chew on everything, these won’t last very long!

The cage should be kept out of direct sun, indoors between 65 and 75 degrees.  The area should have good ventilation but not be drafty.

Diet

A sipper bottle should be provided with clean fresh water, and changed daily.  Guinea pigs should be fed a small amount of pelleted food (about 1 Tablespoon per guinea pig per day).  They should be provided plenty of timothy hay (ad lib, or unlimited!).  The diet should be supplemented with a variety of vegetables.  Guinea pigs require vitamin C in their diet, so make sure to offer items such as peppers, broccoli, and leafy greens such as kale, cabbage, chard, or spinach.

Guinea Pig Veterinary Visits?

We recommend bringing in new pet guinea pigs for a physical exam.  We want to make sure your pig is healthy, and we can discuss husbandry to try to prevent potential problems.

Guinea pigs also require regular nail trims.  The nails on their front paws often curl, and need to be kept short to avoid becoming ingrown.  Their teeth also grow throughout their lives (both the incisors you can see, and the molars in the back of the mouth that are hidden).  Some guinea pigs don’t chew enough hard foods or items, or have crooked teeth, and need to have their teeth trimmed or filed down.

If you have multiple guinea pigs, you may need us to spay or neuter them to prevent unwanted breeding.  If female guinea pigs don’t have babies when young (6-9 months), the fusion of their hip bones will prevent them from giving birth without emergency C-section later in life.

 Guinea Pig Problems

Many guinea pigs will hide their illnesses for as long as they can.  If there is a decrease in appetite, thirst, fecal pellets, activity, or vocalizations, you should schedule a veterinary visit so we can check things out right away.  Some of the common things we’ve seen are:

Gastrointestinal Problems – Guinea pigs cannot vomit, but they do develop diarrhea.  If they stop eating altogether, lethal toxins can form in their gut (ileus).

Growths – Older guinea pigs may form cysts and skin tumors that can be surgically removed.

Injuries – From fights with other guinea pigs, accidents in the cage or house, falls, etc.

Parasites – We often see guinea pigs who have acquired lice or mites.   These cause itchy skin and fur loss.   Severe itch can also trigger seizures.

Respiratory Infections – These cause wheezing, sneezing, and conjunctivitis.

Urinary tract infections – These cause frequent urinations, pain, and bloody urine.  Some guinea pigs also develop bladder stones.
