Can you feed your hamster Jif peanut butter?

No.

Hamsters should not eat Jif peanut butter, especially the sweetened variety. Jif peanut butter contains added sugar, which is unhealthy for hamsters. Hamsters are sensitive to sugar, and eating even small amounts can lead to weight gain and other health problems. Additionally, Jif peanut butter may contain harmful ingredients such as salt and oils that are not suitable for hamsters.

Instead of Jif peanut butter, it's best to provide your hamster with healthy treats specifically formulated for them, such as plain unsalted nuts, seeds, or freeze-dried fruits.
