Is it normal? My two barely drink

[Shalom]

My guinea pigs are just over a year now and only drink 1-2 inches of water a day between them. Once or twice this year they wouldn't stop drinking, got through half a bottle!
I assume this is normal

 

[emmalala]

mine don't seem to drink much either. I suppose they get a lot of water through veg. They certainly wee enough!

I thought mine drank a lot but recently replaced 2 bottles and now they hardly touch it... and it hardly goes down ....I've checked the bottle works ..... maybe my old ones just leaked rolleyes
