[cypher]

All my hamsters seem to prefer to use bowls rather than bottles, I give them both when I first get them but they soon ignore the bottle in favour of the bowls, I use this one which is a really good design, it doesn't tip or spill, perfect size too.
You do need to take a bit of care with where you put it so it won't get knocked over or get lots of substrate in it, I put mine on a shelf & don't have any problems with stuff getting in.
