Hamster water bottle OK for guinea pig?

Answer 1

The only problem would be the size. Guinea pigs drink MUCH more than a hamster would, so generally you would need a larger bottle. Also, if you used this bottle for a hamster previously, you would need to make sure it was cleaned well before using it with another animal.

Answer 2

It is not recommended to use a hamster water bottle for a guinea pig. Guinea pigs require a larger water source, such as a water bottle with a sipper tube or a heavy bowl, to ensure they have access to enough water. Using a hamster water bottle may not provide sufficient hydration for a guinea pig.
