8. Grapes or Raisins
Seedless grapes or raisins are often recommended for little critters, but they can be dangerous. These sweet treats have been known to cause kidney failure. While your hamster may be fine if he eats grapes, you can’t guarantee the fruit won’t affect him. The symptoms can take a while to show up, so you may think your pet is fine until he’s not. It’s not worth the risk when there are so many other good foods to offer.
