How can I make my hamster gain weight?

Making a hamster gain weight is fairly simple. First, provide quality hamster food rich in protein and fat to ensure adequate nutrition. You can also give high-calorie snacks such as sunflower seeds, pumpkin seeds, walnut pieces, and flaxseed. Second, feed on a fixed schedule each day to keep the hamster from burning too much energy from hunger.

You can also increase each feeding amount based on the hamster’s weight and gain goal, but do not overfeed at once to avoid digestive problems. Note that an overweight hamster can develop health issues like heart disease and diabetes, so weight gain should be moderate.
