Over Eaten

If you have given your hamster too many blackberries, you will find that your hamster will have diarrhoea. Depending on how much they have eaten will depend on the severity of harm. If your hamster had had diarrhoea a few times, you must seek veterinary advice. The more diarrhoea a hamster has, the likely chance of dehydration. Dehydration, if not treated, can be fatal to a hamster, and this is why it’s imperative not to overfeed your hamster. It would be best if you stuck to the guidelines when treating your hamster blackberries.

  • Diarrhoea, leading to dehydration!


  • Never leave blackberries in their cage, as these types of fruits can get messy in the cage. 
  • When feeding your hamster blackberries, try chopping them up into smaller pieces, so they have no choice but to eat and enjoy them straight away. 
  • If they start saving the blackberries in their pouches for later, you should stop feeding them.
  • Don’t treat hamsters to other varieties of different fruits on the same day as blackberries.
  • If you have stuck to the feeding guidelines and your hamster still has a little diarrhoea, stop feeding blackberries straight away. All hamsters can have a different reaction to fruit.
  • Wash any fruit that you treat your hamster with, as they can have pesticides on them.
