If you need food or water bowls, look no further than the supermarket chilled pudding aisle! Gu puds do lovely little glass hamster bowls - 2 in a box. The only downside is that it does need the human to empty the chocolate banoffee filling inside them, but I know we're all committed to our hamsters and so would be willing to make such a sacrifice for them

I've had several in use for 2-3 years and they are so sturdy.
