Yes, cats can eat blueberries. Blueberries are rich in antioxidants and fiber and can help support your cat’s immune system and provide them with energy. It's also said that the nutrients found in blueberries may help lower cholesterol levels. As long as you don't give them too many blueberries at one time, they should be fine to eat them every day.

Here are some tips for giving your cat blue berries: -

• Start slow by giving your cat one or two berries at first to see how their stomach reacts.
• Make sure you chop up the blue berries into cubes so it's easier for your cat to chew
• Give them fresh water while they're eating the blueberry snack.
• Don't feed them too many because this can lead to diarrhea.
• Keep an eye on how much they enjoy the snack, if they eat it all then maybe try giving them more.
