answer:

Animals are used in about 7-8 percent of psychological research. Of that, 90% of the animals used are rodents and birds, principally rats, mice, gerbils, hamsters and pigeons. About 5 percent are monkeys and other primates. Psychologists rarely use dogs and cats.

Each year, more than 100 million animals—including mice, rats, frogs, dogs, cats, rabbits, hamsters, guinea pigs, monkeys, fish, and birds—are killed in U.S. laboratories for biology lessons, medical training, curiosity-driven experimentation, and chemical, drug, food, and cosmetics testing.
