Guinea Pigs

Guinea pigs are among the cutest pets that people own. They are members of the rodent family and originate in South America. They are also known by the name “cavy” which derives from the scientific name Cavia aperea. Guinea pigs are born fully haired, eyes open and ready to run. They make great pets for adults and children alike and enjoy the human-animal bond that develops between owners and their pets.

Housing

Guinea pigs are very active pets so buy the largest cage possible. There are cages that are specifically made for guinea pigs that do not have wire on the cage bottom. This is an important feature as guinea pigs can get their feet caught in the wire and break a leg very easily or develop pressure sores on the weight baring surfaces of their feet.

Guinea pigs enjoy playtime and run and jump with obvious joy. They like tossing toilet paper rolls and even some small dog toys around. Providing tubes to run through and little houses to hide in help keep your pet content

Feeding

Guinea pigs prefer using a water bottle rather than a bowl if given the choice. Water bowls also tend to get full of litter and debris quickly so keep this in mind when purchasing your equipment.

Hay should be fed in abundance each day. Timothy, oat, sweet grass, and meadow grass are all very good and depending on the time of year, some if not all will be available. One important side note to remember: alfalfa is the “candy bar” of hays. Too much alfalfa can contribute to gastro-intestinal and urinary tract problems because of high protein content, so feed this type of hay sparingly. Offer dark leafy green vegetables daily as well at one-half to one cup per guinea pig.  This will provide higher levels of vitamin A and increases fluid intake (as well as making life more enjoyable for your ‘pig.  Stay away from carrots and other high sugar foods such as grapes, raisins, bananas, etc.

Guinea pigs have a unique dietary need. Because they can’t synthesize vitamin C, their diet must be supplemented with this vitamin. If they do not get enough vitamin C, they can develop scurvy.  Depending on pellets or vegetables to supply is risky.  Our hospital diagnoses over 50 cases of scurvy a year, most of these cases end with the death or euthanasia of the guinea pig. We recommend using human a vitamin C product and stock and sell it at the hospital. Pelleted foods can also be offered as a treat. one tablespoon given daily should be adequate.

Diseases

The most common problems we are presented with include: scurvy (hypo-vitaminosis C), urinary tract infections and stones, fungal and parasitic skin infections, and teeth problems.  We will cover these problems in separate postings.

  1. One thing to add about water bottle “cleanliness” –

    You can clean your guinea pig’s water bottle with a 50/50 mixture of white vinegar and water. Just let it sit for a few minutes and rinse thoroughly. This will help eliminate any unwanted bacteria or fungus growth that may start to form on the bottle itself.

    Hi I got a guinea pig yesterday its a girl and 3 months old. Do you have any name ideas?

    • I like Priscilla!
      What ever you pick, it should pass my mother’s name test.
      Once you’ve decided on a name you should go outside your house, stand in the street and yell the name as loud as you can for a full 20 minutes. If you don’t feel comfortable doing that you need to pick another name.
      Cheers! Dr. J

  3. I’ve owned about eight guinea pigs over the past twenty years, and I’ve always taken them to Avian and Exotic Animal Hospital. After seeing a sick piggy I’d purchased at a pet store, you recommended I consider Wee Companions next time, and adopt a healthy rescue guinea pig.

    I did this, in 2002. I visited an adoption event at a PetSmart in Encinitas (as I recall.) I went there to get a new pet rat, because one of my two rat brothers finally hit his 1,000 day mark and died. His brother seemed lonely, so I wanted to get him a buddy. The Wee Companions lady, Fionella, as I recall her name, showed me a bonded pair of rats, two neutered brothers, and I purchased them. I also fell in love with little Kailey, a very skittish young guinea pig. Off we went.

    The rats were just lovely pets, enormously fun and interactive. They lived out a normal lifespan. Kailey joined my two other piggies in our large plexiglass enclosure. She stayed in hiding often, but after regular attention and holding, she began to come out and play more.

    You had told me to use Carefresh, not wood chips. You had told me to lace her fresh water with liquid Vitamin C, and feed her only fresh timothy hay, not alfalfa, much as this article mentions. I listened.

    Now it’s 2012, and I’m happy to say that Kailey is with us still. Her cagemates are long gone, most lasting 7 years. Kailey is about 10 now. Her voice is a little quieter, but she still squeals for kale from the garden. I’m not sure she hears too well, but she doesn’t need to. If I let her run around on the floor outside her cage, I have to trick her to catch her — I cannot outrun her. She’s very happy. She coos loudly and continuously when I hold her.

    I credit your sound advice, and my following it, for our having Kailey at all, and for the many years of pleasure we’ve had with her.

    • Wow! What a story! Thank you for your kind words, but it is your good care, some good genes (ad a little good luck) that has been most important to her longevity!
      We see so many piggies with scurvy (vitamin-C deficiency), most of them die! I can’t emphisize to other guinea pig owners how important it is to supplement the diet with vitamin-C.

    I have been feeding my guinea pigs iceberg lettuce once in a while. They have never acted weird after eating it. Someone told me it is poison to guinea pigs. I have had guinea pigs that have lasted 5 to 7 years and fed them iceberg lettuce. Is it true that iceberg lettuce is poisonous?

    • Nothing really wrong or bad about iceberg lettuce, it simply has NO nutritional value.
      I guess if they ate a lot of it they could starve, but that is not likely to happen. It would be much better to feed them a more nutritious fresh vegetable portion of their diet. We recommend what we describe as “dark leafy greens.” Vegetables that are leafy, green and don’t have “lettuce” in their name. Dark leafy greens include dandelion greens, kale, collards, mustard greens, turnip greens, beat tops, carrot tops, parsley, cilantro, etc.

  5. Great site. Plenty of helpful info here. I am sending it to several pals and also sharing. Thank you to your effort!

    Can I feed my guinea pigs beets? They like the beet tops/greens, but I can’t find any food list that includes the actual beets. Also, is it true that potatoes are poisonous for piggies?

    I gave my 9 year old daughter a guinea pig for her birthday. She has been wonderfully responsible for the guinea pig for 4 months. His cage never stinks! Recently the guinea pig developed some respitory problems. We took him to a vet right away and she put him on an antibiotic. He seems much improved.
    My question is about his bedding. We have been using 98% dust free kiln dried pine from the feed store. The vet said this could be the problem and suggested recycled newspapers or Carefresh. These options are much more expensive than the pine. I have been researching the use of a fleece liner with puppy training pads underneath to absorb moisture. When I consulted the vet she said he might eat it. Couldn’t he eat any bedding option? What is your opinion on guinea pig bedding? Thank you so much for your thoughts.

    • You are correct. We see many GP’s kept on fleece or Chucks (under-pads) or the washable variety.

      Washable under-pad

      I agree that the paper bedding, Carefresh, etc., are the best for most people (because most will not care for the bedding as often as the under-pads, fleece, etc. need to be change.

      The pine bedding is a respiratory irritant and may increase the risk of upper respiratory tract problems and pneumonia.

  8. I have 2 Guinea Pigs, both male. One of my males is dragging its back feet and has rapid eye twitching. He is 1 year old. Can you help?

    • Mandi
      Your Guinea pig’s signs are suggestive of disease of his brain and or spinal cord. There are many possible causes from trauma to infectious or metabolic problems. You need to find a veterinarian to take a look at him. We can get a pretty good idea what is going on from a physical exam alone, but tests may be necessary to make a diagnosis.
      Meanwhile, keep him separated from your other pig and make sure he can get to food and water.
      Best of luck! Dr. J

    Dr. Jenkins,

    One of our two sweet little piggies has had a stroke. We have no idea how old they are as they are each rescue pigs. It has been 4 days since the stroke. The first two days she did take water when I put the bottle in her mouth and she also ate twice from the feeder when I put it in her mouth (pureed timothy hay, water and carrot.) But yesterday and today she has refused both food and water though her neck had regained some muscle strength. She just lays on her towel but will move some occasionally. I realize she is in the dying process but I just don’t want her to suffer. Is there anything else I could be doing?
