Interested in adopting a special rescue guinea pig? You’ve come to the right place! Before you submit an adoption questionnaire, here’s some important information you should know about caring for a guinea pig.

Ringworm Exposure

This guinea pig has been exposed to ringworm in their previous home. Ringworm is a highly treatable, non-life-threatening fungus that can be passed to humans and other animals. Ringworm is more likely to affect young or immunocompromised animals and people. Despite its name, ringworm is not a worm. It is a fungus that often causes dry, grey, scaly patches and hair loss. Guinea pigs are treated for ringworm through oral medication.

This guinea pig is not showing signs of ringworm and there is no treatment needed at this time. We recommend that you monitor the animal for any patchy areas of hair loss or flakiness and have your family veterinarian check any areas of hair loss that might occur.

Our Adoption Counselors are prepared to answer your questions and concerns about ringworm during your phone adoption consultation.

About Guinea Pigs

Guinea pigs are social and expressive animals who can live up to 5-7 years when well taken care of. Although popular pets, guinea pigs are very unique and have special needs that can be overlooked by most owners.

As extremely social herd animals, guinea pigs should live with at least one or more guinea pigs to lead a healthy, happy life. Guinea pigs may live together if they are the same sex or a neutered/spayed male-female pair. If you have a guinea pig as a single pet, you will need to spend lots of time with them every day.

We recommend that you spay/neuter your guinea pigs. It is essential to find a cavvy-savvy exotic vet to perform any surgeries for guinea pigs.


Before adopting, consider the space guinea pigs need for their habitats in your home.

  • Most enclosures sold in pet stores are much too small for guinea pigs; an enclosure must be at least 10 square feet for a pair of guinea pigs.
  • Enclosures must have a solid bottom as wire bottom cages can be very painful for guinea pigs and can cause foot sores to develop.
  • Wood shavings can also cause respiratory issues and should not be used for bedding. Instead, use recycled paper or washable soft material such as fleece.
  • Some guinea pigs can also be litter-box trained if provided with a box lined with newspaper and hay.
  • Their habitat should include tunnels, huts and wood blocks to chew on.


Did you know guinea pigs require a special diet? Here’s what your future piggie friend will need daily to live a healthy life.

  • High-quality timothy hay makes up the bulk of their diet and should always be available, along with recommended daily feedings of food pellets.
  • Small amounts of vegetables can also be offered every day, including cucumber, bell peppers, carrots, green leaf lettuce and cilantro.
  • Since guinea pigs cannot produce their own Vitamin C, they must be given a daily dose of a Vitamin C tab or a liquid form can be added to fresh greens.


Like all companion animals, guinea pigs require continued care to keep them happy and healthy. Here are some of the routine care practices.

  • Guinea pigs are very social animals that require lots of time with their person.
  • They should be given wood blocks to help wear down their teeth.
  • It is essential to use proper bedding in your guinea pig habitat. Improper bedding can lead to respiratory disease.
  • Regular nail trims will help keep your guinea pig from developing health problems. Nail clippers used for people are safe to use for piggies.

Adoption Process

To get started, submit an adoption questionnaire from the individual pet’s profile. From there, our Adoption team will email you a scheduling link to set up a time to talk on the phone to discuss needs specific to guinea pigs and whether the pet will be a good fit for your lifestyle.

If you are ready to move forward with the adoption after your phone consultation, an appointment will be set up for you to pick up your guinea pig at OHS. You will also pay your $15 adoption fee per guinea pig at this time. Our Adoptions team will be doing contactless adoptions and the guinea pig will be brought out to you.

Important note: Please add [email protected] to your address book to ensure you don’t miss any important communications from us.

OHS is also working with our adoption outreach partner, Petco, to find homes for a limited number of guinea pigs. Visit the Petco’s Jantzen Beach location to meet the available guinea pigs and to fill out an OHS adoption application.
