Our two 1.5 yo female guinea pigs are drinking less and less water, but seem quite healthy and happy. They do demand quite some lettuce, so I think that's their main source of water now. Should we be concerned about this? They used to drink reasonable amount of water (perhaps 70% normal amount people say) but now together they drink perhaps one ounce a day. I'm thinking maybe getting a new water bottle to try. Or maybe they didn't get enough exercise, being in the cage most of the time, should we let them run around in the basement more?
Thanks!
Thanks!
