As a laboratory animal caretaker, your job is to monitor and care for each animal within the lab. In this role, you may examine each pet, clean their cage, provide basic veterinary care, and otherwise support lab research efforts. Many details of this job depend on the purpose of the lab, but the job generally involves being as humane as possible with all test subjects. Laboratory animal caretakers may care for a few animals for an extended period or a larger number of animals over a short period. Laboratory animal caretakers often examine animals for signs of illness or injury, use and sterilize equipment, provide routine post-operative care, and prepare samples under the supervision of senior veterinarians or laboratory animal technologists.
