While spinach is a healthy green for humans, it contains oxalates, which can be harmful to hamsters. Oxalates can bind to calcium in the body, leading to:
* Kidney stones: Oxalates can form crystals in the kidneys, leading to painful kidney stones.
* Calcium deficiency: This can weaken bones and lead to other health problems.
What to feed your hamster instead:
* Fresh vegetables: Offer small amounts of other leafy greens like romaine lettuce, kale, and parsley.
* Fruits: Provide a tiny piece of fruit like apple, banana, or strawberry.
* Hamster pellets: This should be the staple of your hamster's diet.
* Seeds and nuts: Offer these in moderation as treats.
It's always best to consult with a veterinarian about your hamster's diet and any specific concerns.
