if your hammy is having hair loss
first go to the vet. You also should watch it and see if the bald spot gets bigger. It might be because of your hamsters age, they live about 2 years, but that doesn’t mean your hamster is going to die on its 2nd birthday- my hamster is 2 and a half he also had some bald spots on his back and now he doesn’t have hair on his neck but that’s because he scratched it off on something sharp but hes fine . Though sometimes it is cancer. it is usually because they are older. remember:
Your first and primary source of information and health care is the vet. check with vet. before you change your pet’s medical care. This information is meant as a helpful tips not as a treatment, diagnosis or replacement of veterinary advice.
