Why is my hamster not eating and acting less energetic than usual?

Updated On September 23rd, 2025

Pet's info: Small Animal | Hamster | Male

My hamster is not eating at all and he is not as energetic as he use to be when I got him. Once I put his food in his bowl he just hides it or when I put him in his ball to run around the house he just stops by his cage and does not do much.

I am sorry to hear about Simba! I would consider putting small amount of food into the bowl and counting or weighing if you have a small gram scale to see if he is truly not eating. If he allows you to handle him you can also try to look in his mouth as they often do store food in the cheeks and if he has food there is probably is still eating maybe just not when you observe. If he truly isn't eating I would recommend an examination at a vet who sees pocket pets, as there can be many different causes for these symptoms and a physical examination is needed.
