1) The decreased water consumption could actual be he’s drinking a normal amount of water now, because he no longer needs to drink water as heavily to lubricate an uncomfortable dental situation. Wick ramps up his water intake the week prior to his regularly scheduled grindings because it’s soothing for rabbits to have excess moisture in their mouth to smooth over and relieve potential sores or sharp edges.
2) Hay decrease can always be a variety of things. You could be at a bad spot in the bag, the hay may be less fragrant now, etc.. It also could actually be teeth related. Although he may not have difficulty eating it visibly, incisors are helpful to pull in pieces of hay into the mouth, so he may no longer perceive as many “prime” hay strand candidates because he acknowledges he cannot readily eat as much. Wick’s hay consumption decreases the week prior to this regularly scheduled grindings. He still eats hay fine, but his dental discomfort discourages it. Since this is a permanent operation, potentially he just needs to get used to it. Starting a fresh bag of hay and mixing it in would be a good way to encourage more hay consumption, and putting more space between non-hay food presentations is helpful as well.
