Why is my hamster suddenly biting and freaking out when I pet her?

Updated On September 23rd, 2025

Pet's info: Small Animal | Hamster | Female | unspayed | 0.25 lbs

Lately when I go to get Princess from her cage to put her in her ball she freaks out when I lay a finger on her. She runs in her cage and jumps and flips when I touch her. She even bit me and made me bleed today. Is she okay??

Any sudden change in behavior should be addressed by your veterinarian. Frequently, illness or injury are the cause. Look Princess over for any obvious signs of injury. Try not to get bitten again. Survey the area in and around the cage for any negative stimuli. This may include loud noises, strong vibrations, bright light, cold drafts or high traffic. Reduce or eliminate any if found. Wash your hands thoroughly before handling her, especially if you have other pets. Their scent may cause her stress. Rub some of her bedding in your hands to get her scent onto you and approach slowly. If she stresses out, stop and try again later. Move slowly and talk softly around her. Offer small treats and allow her to come up to you. Be patient and consistent. It may take time for her to become comfortable with you again.
