Dogs and cats are best friends for many people, but not for students who live in a tiny dormitory room. Just think about the noise, the smell and all that reckless behavior ― chewing on whatever they can get their teeth on, or knocking over the trash can and scattering the contents all over the floor.
But don’t fret. There are smaller and less destructive pets to brighten up your dormitory life, just make sure you’re allowed to keep one.
Originally from Southeast Asia, betta fish were introduced to aquariums in the early 1900s. They make great pets with their big personality and stunning colors, ranging from vibrant bright red, dark blue to lemon yellow.
Unlike many fish, most bettas react to their owner’s presence and become more active when they are nearby, which is unusual in the fish world.
Bettas can be your best friend for up to four years as long as you take good care of them. Although part of their appeal is that they can be kept in a small container without complicated filtration systems, taking care of betta fish does require some effort.
Odorless, about the size of a rabbit and with fur so dense that they can’t get pests such as fleas, the friendly creature originally from the Andes Mountains in South America makes an ideal indoor pet. Chinchillas are very social animals, so if you only have one, you will become its family.
Land hermit crabs
In a society where owners are often asked “Are they tasty?”, land hermit crabs are among the most unlucky animals commonly kept as pets. But they are easy to care for, inexpensive and fascinating to watch. And the fact that they don’t smell or cause any allergic reactions makes them perfect for college dormitories.
If you’re interested in a lifelong friend, a red-eared slider makes a wonderful pet. If well cared for, they can live for around 40 years.
But before you decide to get a turtle, there are a couple of things you should know. Red-eared sliders can get big. Don’t be fooled by those tiny, cute hatchlings – they can grow to an adult size of up to 30 cm! And you should never release it into the wild, even if you get tired of it, because the exotic species can damage local ecosystems.
