Why is my hamster shaking? When pet parents should be worried

Here are the reasons why your hamster might be shaking and this is what you should do about it

It’s certainly a terrifying sight to find your hamster shaking. Just as it would sound the alarm if a human were shivering uncontrollably, so, too, should you leap into action with your pet. However, it can be tricky to nail down the exact cause, and a trip to the vet won’t hurt if you don’t spot an immediate explanation. While illness does lead to the shakes at times, you’ll want to look into a few more of the mundane triggers first to rule that out. When you wonder, “Why is my hamster shaking?” look at these options to determine the issue.

Why is my hamster sitting still and shaking?

No one reason applies in every case, so you need to do a bit of detective work. We’ll start with the most common reasons — which are also the least scary.

He’s frightened

Lots of times when hamsters shake, it’s from fear. Things that don’t look (or smell) scary to you could set your hamster off with seemingly no notice. Try to perceive the world through the eyes of a small pet to figure out what’s troubling him. For example, a dog or cat scent could send him into panic mode even as you struggle to perceive it. Those are his predators! Remove the offending object or beastie and see if he returns to normal.

He went into hibernation

If you can cross fear off the list, think next to the temperature of the room. In the wild, hamsters hibernate, and they’ll immediately slip into that mode when it gets too chilly. You most likely don’t want your hamster to go down for a long sleep, and it probably isn’t safe for him to remain inactive. Maintain a consistent temperature in the room and include a thermometer in or right next to the cage. Select a good area of the house as well that doesn’t have too many drafts and isn’t too close to a radiator. If you do walk into a freezing room and find your little guy zoned out, return the temp to normal (slowly) to spark him out of his hibernation. There will almost certainly be some shaking during this process, but it’s not a concern. Once he gets back to normal, it’ll stop. If it doesn’t, that means something else is going on. 

It’s a medical condition

Hamsters get colds — sometimes lots of them. Examine his physical symptoms aside from the shaking to check for the sniffles. Seriously, he might sneeze and cough and get a runny nose just like you would. While hamster sniffles are a bit cute, the little guys can actually die from colds or other infections. Don’t just check his sweet face, though; you also want to monitor his backside and spot diarrhea or other stomach problems quickly (especially wet tail, which kills hamsters in less than 48 hours). The shaking could stem from diabetes, nervous system disorders, or stroke. Pay close attention to all the symptoms as a whole to narrow it down.

How do you know if a hamster is dying?

Again, we do suggest seeking out an expert here. Especially if you can’t quite find the definitive origin of his shakes. Sadly, sometimes shaking, particularly when combined with lethargy, can indicate that his life has come to an end. In addition, many pet rodents will begin to hide more as they wind down. Give him a checkup on your own and try to spot glaring issues like skin problems or weight loss that might tell you his time is up. And remember that hamsters live only a few years — if yours is pushing 4, it’s more likely to be serious. 

Anytime you discover a shaking hamster, you should go through a process of elimination and start with the simple explanations first. But before you freak out, it could be nothing at all. Don’t mistake excited quivers for true scary shakes. If you just got your pet and he seems jumpy, that may be totally normal. Once you get used to each other, you’ll know what his baseline is. When your hamster can’t stop trembling, that’s when you should investigate and get to the root of the problem, hopefully with the help of an animal doc.

Once they're getting close to the end, though, you'll want to help ease their passing, keeping them warm and comfortable.

By paying close attention to the signs of a dying hamster, you can be ready to step in as a pet parent and help them finish the end of their life well. Watch out for any of these symptoms, which should be accompanied by a visit to the vet, since they can have a few different causes.

Is my rabbit pregnant? 5 telltale signs you should know
Look for these signs to confirm your rabbit will soon have babies

What's better than one pet rabbit? An entire litter of bunnies (as long as you're prepared for them, of course). If you've been wondering, "Is my rabbit pregnant?" now is the time to find out for sure. After all, you don't want to be caught unaware and suddenly have a whole new colony of animals in your hutch.

Sometimes, lady bunnies can take on the behaviors of expectant mamas, but it's actually a false pregnancy. The best way to find out if your rabbit is pregnant is to take her to the vet and have them confirm it. However, when you're figuring it out yourself, you should look for the signs that a rabbit is pregnant. If you spot these behaviors, be sure to call your animal doctor.

What you need to know about sugar gliders before you get an exotic pet
Follow these steps to set your sugar glider up for success

Choosing a small pet involves almost as much deliberation as selecting a breed of dog. While there are a lot of factors to take into account, a sugar glider might turn out to be the perfect fit with their curious personality, attachment to your family, and fondness for pockets.

Like any exotic pet, gliders require expert care plus some dedicated research to choose the right breeder or pet store. But with the right prep, your new mammal will fit in perfectly and bond with the whole family. Keep reading to find out if sugar gliders are good pets.
What are sugar gliders?
Unlike most little pets, sugar gliders aren't rodents but marsupials. This gives you a few distinct advantages, as they behave differently from hamsters, guinea pigs, or gerbils. For starters, these are highly social creatures and they will bond with every member of the family and even other pets in the house. Because gliders don't smell like the animals your cats and dogs like to chase — rats, gophers, and bunnies, to name a few — many bigger pets can get along with your new friend. You'll need to introduce them carefully, but they can form lifelong attachments to each other.
