Three to four days. But that’s a miserable existence. They’ll survive like a dry sponge in a desert. It’s possible, but cruel.
Aim for zero days. Always have water available. Make it a habit. Your fuzzy roommate depends on you.
Remember: hamsters are tiny, fragile, and full of sass. Don’t let them turn into tiny mummies. Give that water bottle a daily check. Your reward? A hyperactive little bean that runs on a wheel at 3 AM, happy and hydrated.
And isn’t that the dream?
