Unfortunately, it becomes far less cute for hamster parents when their nighttime playtime keeps us awake all night.If you’re wondering if there’s a way to train your hamster to adjust to a more human sleep cycle, you’re not alone.In this post, I will share some key information about hamsters and their sleep habits, including why your hamster is so active when the sun goes down. Plus, I’ll share tips and tricks to create a happy home for both you and your hamster – including gear that has helped me coexist peacefully with my hamsters over the years.With a few minor changes or updates, you can share your life with a hamster and enjoy a good night’s sleep. I promise! Why is My Hamster So Active at Night? Since bringing your hamster home, you may have noticed that they are most active at night, catching up on their sleep throughout the day. If you’ve been searching for answers (which you probably are, if you’re reading this), you may have seen many people explaining that you’re experiencing this schedule because hamsters are nocturnal – meaning they are active at night and sleep during the day. However, this isn’t entirely accurate. Hamsters are actually crepuscular. This means that (according to Cambridge Dictionary), they are “active or appearing at the time of day just before the sun goes down, or just after the sun rises, when the light is not bright.” With pet hamsters, this is often mistaken as nocturnal because we are asleep during that period between dusk and dawn. Therefore, we don’t experience them slowing down or resting during the middle of the night. Returning to the original question: “Why is my hamster so active at night?” The short answer is this behavior is the result of their biological wiring. In the wild, they are active when it is safer to emerge and seek out food. This allows them to hide when predators are more likely to see them in the daylight hours. Are All Hamsters Active at Night? As with any behavior, there are always going to be exceptions. If you were to interview 100 hamster parents, you are likely going to find one or two that “break the rules” and are active during the day. However, this is rare. It’s safe to assume that any hamster you adopt and bring home will be most active at dusk and dawn, not during the daylight hours. Can You Change a Hamster’s Sleep Schedule?It is possible to change a pet’s sleep cycle. However, there is no guaranteed approach that will work with every hamster. It’s also not recommended by experts as this process could cause significant stress and anxiety to your hamster by forcing them to go against their instincts. Rather than changing your new pet’s sleep schedule, it’s recommended that you instead focus on making changes to their habitat to accommodate their natural sleep pattern. Does this mean your hamster will always be active at night? Not necessarily. Over time, you may see your hamster adjusting their sleep schedule to better align with your schedule without trying to make a change yourself. But it should not be forced on them. Influencing Your Hamster’s Sleep Schedule While it’s not recommended that you train your hamster to completely change their sleep schedule, you can take steps to influence it and encourage them to adjust slightly to your routine. The best approach to influencing your hamster’s sleep schedule is to encourage them to stay awake and play when they are already awake, not waking them up if they have fallen asleep. Hamsters are startled easily due to their poor eyesight, which means waking them up could trigger severe anxiety. If your hamster is awake at a time that suits your schedule and routine, take the opportunity to spend quality time together while encouraging them to stay awake longer. This could mean playing with them or giving them lots of affection if they are tame and like to be handled. This should be done gradually, keeping them awake just a little longer each day. As you encourage these changes, watch carefully for any signs of stress and anxiety, such as: Loss of appetite Refusing to drink water Increased vocalizationHiding constantly, especially during hours when they are usually activeLethargy or loss of energyFailing to chew and wear down their teeth, overgrown teethChewing at the cage bars Hair loss, bald spots, overgroomingObsessive behaviors like digging, scratching, or lickingUncharacteristic aggressionIf you notice any of these signs, take a step back. This could indicate that you’re pushing your hamster to make changes too quickly or that they aren’t comfortable changing their sleep schedule at all. Reevaluate your efforts and make a decision that prioritizes their quality of life. If that means abandoning this attempt and focusing instead on changing their habitat to minimize noise, that may be the best solution for everyone.
