===Senses===
Hamsters have poor eyesight; they are [[nearsighted]] and [[colorblind]].<ref>{{cite book |author=LeeAnne Engfer |others=photographs by Andy King |title=My pet hamster & gerbils|year=1997|publisher=Lerner|location=Minneapolis|isbn=978-0822522614|page=13}}</ref><ref>{{cite book|title=Concise encyclopedia biology|year=1995|publisher=Walter de Gruyter|location=Berlin|isbn=978-3110106619|page=[https://archive.org/details/conciseencyclope00scot/page/299 299]|edition=Rev.|author=Thomas A. Scott|url=https://archive.org/details/conciseencyclope00scot/page/299}}</ref> Their eyesight leads to them not having a good sense of distance or knowing where they are, but that  does not stop them from climbing in (and sometimes out of) their cages or from being adventurous. Hamsters can sense movement around at all times, which helps  protect them from harm in the wild. In a household, this sense helps them know when their owner is  near.<ref name="omlet.us">{{Cite web|url=https://www.omlet.us/guide/hamsters/about_hamsters/anatomy/|title=Anatomy {{!}} About Hamsters {{!}} Hamsters {{!}} Guide {{!}} Omlet US|website=www.omlet.us|access-date=2019-11-20}}</ref> Hamsters have [[scent glands]] on their flanks (and abdomens in Chinese and dwarf hamsters) which they rub against the surface beneath them, leaving a scent trail.<ref>{{cite book|last1=Bartlett|first1=Patricia Pope|last2=Earle-Bridges|first2=Michele|title=The Hamster Handbook|publisher=Barron's Educational Series|isbn=9780764122941|page=[https://archive.org/details/hamsterhandbook00bart/page/21 21]|url=https://archive.org/details/hamsterhandbook00bart|url-access=registration|language=en|year=2003}}</ref> Hamsters also use their sense of smell to distinguish between the sexes and to locate food. Mother hamsters can also use their sense of smell to find their own babies and identify which ones are not theirs. Their scent glands can also be used to mark their territories, their babies, or their mate.<ref name="caringpets.org">{{Cite web|url=https://www.caringpets.org/how-to-take-care-of-a-hamster/behavior-body-language/|title=Hamster Body Language & Behavior: What it Means|website=Caring Pets|language=en|access-date=2019-11-20}}</ref> Hamsters catch sounds by having their ears upright. They tend to learn similar noises and begin to know the sound of their food and even their owner's voice.<ref name="omlet.us"/> They are also particularly sensitive to high-pitched noises and can hear and communicate in the [[ultrasound|ultrasonic]] range.<ref name="Fritz"/>
