Whether you’re in California, Texas, or somewhere afar, hamsters are great pets to have. Although hamsters are easy to take care of, it’s still essential that they remain hydrated and fed throughout the day. But what if your hamster isn’t drinking water—is that something you should worry about?
Your hamster might not be drinking water because it’s under emotional or physical stress. Hamsters react to their emotional health physically, and new experiences and stressors can create a lack of appetite and dehydration. That said, keeping your hamster happy is crucial.
Keep reading as I discuss why your hamster may not be drinking water throughout this article. I’ll also give tips and tricks for helping your hamster return to proper health.

Your Hamster Won’t Drink Water if They’re Stressed or Unhappy
It can seem frightening when your favorite pet avoids drinking their water or eating their food as they usually do. The good thing is that there’s a reason for it.
Hamsters won’t drink their usual water intake if they’re under any stress or if there’s a change in their lives. This process may occur from a wide range of different things:
- Your hamster may be reacting negatively to a change in its diet.
- Your hamster could be struggling to drink from their bottle.
- It may just be a fluke, and your hamster isn’t drinking as much as expected.
- Your hamster may be around new things, such as another hamster.
- You just brought your hamster home, and they’re your new pet.
- Your hamster will reach if you’ve moved it or there has been a change in their environment.
- Your hamster could potentially be sick, or they might not be feeling well.
It’s also important to remember that hamsters don’t drink a ton of water.
On average, hamsters need around two tablespoons (30 mL) of water a day, depending on their weight, to maintain healthy hydration. If your hamster isn’t drinking, they may be able to last around 48 hours before reaching peak dehydration.
If you suspect that your hamster isn’t drinking water, don’t hesitate to consult your local veterinarian after 24 hours. Vets are available all around the U.S., with California being the top city for veterinarians.
You should be able to find one that can check your hamster and advise you on what to do to make sure your hamster drinks again.
