I bought 2 of these to replace 2 older Perky Pet, 4 flower models.  The old 4 flower model has a design flaw which sometimes led to dripping and also attracted ants and wasps.  The bottle is large but the plastic bottom holds a lot of fluid as well.  It is over-sized for our needs, so I just fill it with less food.  Perky Pet should consider creating a new model based on this design but smaller.
