Yes, hamsters can eat cheese!
Cheese should not be a significant part of your hamster’s diet and you should not feed cheese to your hamster too often.
However, feeding cheese to your hamster as a treat, perhaps once per week in small quantities, should be fine.
Before feeding your hamster a significant amount of cheese, you should first make sure that your hamster doesn’t have a bad reaction to it. You do this by feeding them a very small amount as a test.
The cheese that you feed to your hamster should be mild and low in fat.
If your hamster shows no signs of sickness or diarrhoea for a couple of days after eating the small test amount of cheese, then you can go ahead and add it to their diet as an occasional treat.
As well as hard cheeses, you may also be interested to know that hamsters can eat small quantities of cottage cheese. But again, you should choose a low-fat variety and feed a test amount before feeding cottage cheese to your hamster more regularly or in larger amounts.
