Events this Season

Insect Buffet (Nov. 1-30): Explore the various ways insects eat their food of choice. You can be especially grateful during your Thanksgiving meal that you won't have to slurp up turkey using a mosquito's syringe-like mouth!

Cockroach Mazes (Dec. 1-31): Create mazes for Madagascar Hissing Cockroaches to scurry through.  Can they get through faster than a robotic insect?

Exciting Animal Updates

Meet our new guinea pig additions, Truffles and Cream Puff!  They were born to their mom Pattie Cake in July of this year.  They'll be making their transition to becoming animal ambassadors slowly, but will make the occassional appearance during our Public Program hours this fall.  They love to be together and will squeak away anytime they're apart or think they smell their favorite treats being prepared for them.

Adopt Animals or Make a Donation

Adopt an Animal

There are a number of animals in the Animal Discovery Room that have served us well for many years and are now ready to retire from the world of education. In some cases, we have more of one species than we really need. We are looking 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.

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 set up and food for the animal prior to picking it up.
  3. You must pay the $15.00 adoption fee for most animals. Mice are a $5.00 flat adoption fee, regardless of how many are adopted at once. Rats are $5.00 each.

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

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 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 members of the public.  We also occasionally accept used animal enclosures as long as they are in good condition.

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. 

We Care About Our Animals

Special care is taken to ensure that all of our animals are housed correctly, with the proper substrate, heat, light, humidity, and enrichment. Undergraduate Animal Discovery Room (ADR) helpers, with the assistance of teen interns, conduct daily checks of all ADR animals.  Helpers and interns are the first to notice any changes in the animals’ behavior or physical appearance. If there is a behavioral or physical change in an animal, it is monitored and may receive vet care depending on the severity of the situation. In order to monitor all of the ADR 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 animal care and USDA regulations. Veterinarians are available 24/7 to provide quality veterinary care and advice. They do routine checkups on all of the animals, as well as operations and x-rays, and provide other veterinary services.
