![]() The best part is that it is made of wooden material. This box has a total of 16 holes and 13 compartments. To make sure that they finish the entire maze, you can use food to lure them into the next hole. In many science classes, people use hamster mazes to train their pets to do different tricks. It is also a good way to study the behavior of your pets. The hamster maze will not only keep your pets busy but also make their brains active. This is why a hamster maze will entertain them because it resembles a tunnel they would make if they are in the wild. Rodents love to burrow because this is what they would do in the wild. If you’re not familiar with it, it is basically a box with multiple tunnels where the hamster can get in to. One way you can do that is by letting them play in a hamster maze. Just like other pets, hamsters are animals too and they need their exercise. However, the challenge with keeping tiny pets such as hamsters is that you have to keep them in a cage most of the time. Those who managed to control space led relatively normal lives.”Ĭalhoun’s work didn’t give us answers, but it is rare that any single study or series of studies can draw definite conclusions.Teach your pet hamster some tricks with this Hamster Maze Wooden Box! It is also suitable for other small pets such as mice! Many people prefer small pets because they won’t take up too much space in their homes. “Not all of Calhoun’s rats had gone berserk. ![]() Moral decay could arise “not from density, but from excessive social interaction,” Ramsden says. His work suggested a different interpretation. "Calhoun’s research was seen not only as questionable, but also as dangerous.” Another researcher, Jonathan Freedman, turned to studying actual people - they were just high school and university students, but definitely human. Ultimately, “ats may suffer from crowding human beings can cope," Ramdsen says. The NIH Record spoke to medical historian Edmund Ramsden about Calhoun’s work: She writes, " Instead of a population problem, one could argue that Universe 25 had a fair distribution problem."īut we can take comfort in the face that humans are not mice. Inglis-Arkell explains that the habitats he created weren’t really overcrowded, but that isolation enabled aggressive mice to stake out territory and isolate the beautiful ones. Now, interpretations of Calhoun’s work has changed. Frisby and the Rats of NIMH, which was also made into a 1982 film The Secret of NIMH, notes the National Institutes of Health. The work also inspired the 1971 children’s book Mrs. A host of science fiction works - books like Soylent Green, comics like 2000AD - played on Calhoun’s ideas and those of his contemporaries. The work tapped into the era’s feeling of dread that crowded urban areas heralded the risk of moral decay - and events like the murder of Kitty Genovese (though it was misreported) only served to intensify the worry. The unusual behaviors he observed he dubbed "behavioral sinks."Īfter Calhoun wrote about his findings in a 1962 issue of Scientific American, that term caught on in popular culture, according to a paper published in the Journal of Social History. ![]() When the population started declining the beautiful ones were spared from violence and death, but had completely lost touch with social behaviors, including having sex or caring for their young.Ĭalhoun’s experiments, which started with rats an outdoor pen and moved on to mice at the National Institute of Mental Health during the early 1960s, were interpreted at the time as evidence of what could happen in an overpopulated world. The few secluded spaces housed a population Calhoun called, "the beautiful ones." Generally guarded by one male, the females-and few males-inside the space didn't breed or fight or do anything but eat and groom and sleep. Sometimes they'd drop and abandon a baby while they were carrying it. They'd move half their litter away from danger and forget the rest. Few females carried pregnancies to term, and the ones that did seemed to simply forget about their babies. They gathered in the main squares, waiting to be fed and occasionally attacking each other. But what looked like rat utopias and mouse paradises at first quickly spiraled into out-of-control overcrowding, eventual population collapse and seemingly sinister behavior patterns.įor io9, Esther Inglis-Arkell writes about Calhoun’s twenty-fifth habitat and the experiment that followed:Īt the peak population, most mice spent every living second in the company of hundreds of other mice. These were all part of John Calhoun’s experiments to study the effects of population density on behavior. What does utopia look like for mice? According to a researcher who did most of his work in the 1950s through1970s, it might include limitless food (of course!), multiple levels and secluded little rodent condos.
