We have 2 outdoor rabbits together in the hutch. Previous owner used water bowls. But they are always getting poop and hay etc in them. So we recently put in a regular ball type water bottle and were so excited when they both figured out how to use it. The metal spout freezes fast though so ordered a heated bunny water bottle on amazon. The spout is slightly different with a little stick thing in the middle to move. It moves easily and the water comes out fast but bunnies can't figure it out. Just keep licking the spout. Afraid they are going to dehydrate if we don't put old one back but will never learn if they have that choice. What to do?
