I switched out my bunny from using a water bottle to a bowl recently and I’m not sure how to really tell how much water he is drinking. I left the bottle in there just in case he doesn’t like the bowl and would rather that so at least he drinks some. He hasn’t drank out of it so I figured he likes the bowl better but how do I tell if he is drinking enough? It’s not empty every morning when I go to feed him and I’ll clean it out just so it is fresh but should it be empty or at least like halfway? I feel like he drank more water when it was just the bottle.
