Bowl or Bottle

[CanadianCavy]

I got twogirls two weeks ago and I have had a bottle and water bowl available to make sure they were comfortable to keep hydrated. I have only watched one of them drink from the bowl everytime and never the bottle. (the other girl I never see come out at all lol)
If I want them to use the bottle in the future is it okay to remove the bowl or will that risk them not drinking at all?

As long as the bottle is working ok then the piggies will work it out.
I started my lot with a bowl and bottle and found the bowl got very messy very quickly, so I just removed it and they were all fine.
