When a boarder comes in I always ask whether they're used to a bowl or bottle. If the owner says bottle, I will put a bottle on but always put a bowl in too. If they say bowl, just a bowl goes in.
For the boarders which have come in used to a bottle, 100% of them have ignored the bottle all week and drank exclusively out of the bowl :lol: (I always let the owner know and all owners this has happened to have been pleasantly surprised and subsequently switched to a bowl)
Now when new boarders come and say they've tried their bunny with a bowl 'but they prefer the bottle' I always nod and smile sweetly and put a bowl in anyway as I am pretty certain that during their stay they will switch to the bowl
:lol:. I think the issue with some people is they use small plastic bowls that are low to the floor and light so bunny simply knocks them over or get poo/bedding in them, so the owners think they don't like it/want to drink from it and remove.
So, a 100% firm believer that given the right kind of bowl (one that's the right height, and heavy so they can't knock over) a bunny will always prefer a bowl (well, in my experience anyway)
