We've recently got two dwarf lop rabbits who are about 7 weeks old. I gave them their water in a bottle attached to the side of the cage but the level didn't seem to be going down at all. It's a bottle with a little metal ball in the tube to stop the water leaking out. I'm not sure that they are getting much water from it - they just appear to lick the end of the tube. So i've just given them a little water in a small bowl and they loved it and lapped it up. So should i be giving babies this age their water in a bottle or bowl?
