Yes, hamsters can absolutely eat fish.
Fish contains protein and fatty acids that are necessary for the hamster.
Do not even think about giving your hamster oily, deep-fried fish though! All of the good oils will be lost in the frying process.
If you are going to feed your hamster fish, make sure it is baked or boiled without any added oil or seasoning.
How is fish good for hamsters?
Fish is good for hamsters because it has oils that the body can use to produce energy. It also contains protein, which is necessary for your hamster’s healthy growth and reproduction.
Can fish be bad for hamsters?
Like anything else, it depends on the hamster’s taste for fish. Some may love it and eat as much as you are willing to give them. Others, not so much.
If your hamster does not seem interested in the fish you offer it, try serving it in different ways or with different seasonings to entice its appetite.
If you are worried that the fish will not be good for your hamster, feed it a tiny piece first to see if there are any digestive issues. This is especially important if your hamster has already been sickened by something in the past!
