+ Featured Animals

Baby Guinea Pigs

Truffles and Cream Puff are our youngest Animal Ambassadors. They were born to their mom, Pattie Cake, in July of last year. They have now grown up enough that they no longer depend on their mother and have been moved to a new enclosure that they share. Truffles is a little more outgoing than Cream Puff, and it's been fun to watch their personalities develop over the past several months. They are quite vocal when they smell fresh veggies being chopped up for their treats, and each one quickly grabs her favorite leafy green and scurries under her personal "igloo" to munch in peace. Occasionally they play a bit of tug-of-war for a leaf, but usually one will eventually give up and find another scrumptious treat to eat.

+ Adoptions

Adopt an Animal

The Animal Discovery Room contains a number of animals that have served us well for many years and that are now ready to retire from the world of education. In some cases, we have more of one species than we actually need. So we look for permanent homes for these wonderful animals. A small adoption fee helps ensure that each animal goes to a family that is ready to take on the responsibility of adoption. Below is a current list of adoptable animals as well as criteria for adopting them.


Sorry, there are no animals available for adoption at this time.

Sorry, there are no animals available for adoption at this time.  

Criteria for Adopting

  1. You must set up a time with the Animal Discovery Room Manager to talk about species-specific enclosure requirements and the animal's husbandry needs and history.* See Contact Us page for general contact information.
  2. You must provide your own enclosure with proper setup and food for the animal before you pick it up.
  3. You must pay the $15 adoption fee for most animals. Mice are a $5 flat adoption fee, regardless of how many are adopted at once. Rats are $5 each.

*Note: Not all adoptable animals are recommended for households with small children.

+ Donations

Make a Donation

Many of the animals in the Animal Discovery Room (ADR) have been donated by patrons of the Lawrence Hall of Science.

We do accept animal donations on occasion but, due to space limitations, we carefully screen all animals before they become a part of our teaching animal collection. ADR animals must be easily handled and even-tempered, since many are used in classes with children and other members of the public. We also occasionally accept used animal enclosures as long as they are in good condition. If you would like to support the care of our animals by making an online monetary donation, please fill out our secure online contribution form, and specify "For the Animal Discovery Room" in the Additional Details section. 

We house more than 50 species of animals and attempt to maintain variation in the ADR when accepting animal donations. Please contact us if you are interested in donating your animal or used animal enclosure to find out if it meets all of our criteria. 

+ Care

We Care About Our Animals

Special care is taken to ensure that all our animals are housed correctly, with the proper substrate, heat, light, humidity, and activity enrichment. Undergraduate Animal Discovery Room (ADR) helpers, with the assistance of teen interns, conduct daily checks of all animals. Helpers and interns are the first to notice any changes in the animals’ behavior or physical appearance. If a behavioral or physical change is noted in an animal, it is monitored and may receive vet care, depending on the severity of the situation. To monitor all the animals, we conduct monthly weight checks. New or sick animals are weighed weekly to ensure that they are adjusting well and staying healthy. When needed, we administer medicine, supplied by our veterinarians.

UC Berkeley Office of Laboratory and Animal Care (OLAC) veterinarians provide care for all our animals according to campus and USDA regulations for animal care. Veterinarians are available 24/7 to provide quality veterinary care and advice. They do routine checkups on all the animals, as well as operations and x-rays as needed, and provide other veterinary services.
