Amount of water on average ?.

Hello,

 

 I am writing to you because I am worried about the water consumption that my guinea pigs drink daily. They both consume 500 mL of water every 24 hours. Before what was ready 350 mL. And it's hell how she urinates, I had to redo the litter change today, the last time was on Saturday and it smells really strong ... how much water your guinea pigs consume you ?

 

thanks
