Hi Lut, I Like that fountain too! But I don't know it will work for me as the electrical voltage in the USA is 110V and we have a 220V. in Spain.What's the voltage in Belgium?.
For the plug there's no problem you can easily find a conveter in a shop supplies for traveller's or in a hardware warehouse.

Sometime before buying for my furkids I check at Petco. or Petsmart. and the goods are the same and the price are similar thought in the USA there's more choice,I'm pretty sure it will arrive here too!

Anyway there's a link
http://www.petsmart.com/products/product_27291.shtml and you can check what it cost to send it overseas.
