Hi guys. Im at a loss and need some help. I have a less than 1 year old Holland Lop, Buggy. Since 2/3/2023 she has stopped drinking water voluntarily. We immediately re-cleaned her water bottle and added a water bowl to see if she would like that (she has always used a bottle before, she never liked bowls). We started syringe feeding her water the same day to ensure she was getting at least a little bit of water in her system. The next day her pee and poop production slowed down. She completely stopped peeing, but would poop every now and then but not as much as she normally does. She was still eating her vegetables, pellets, and hay normally, and acting like her normal self, she just would not drink or potty regularly. She did poop some over the weekend (again not as much as normal) but would not pee. We continued this process of syringe water and cleaning water bottles and bowls at least 2 times a day over the weekend until we could get her to vet. On Monday 2/6, we took her to the vet (mind you, we are in a small town, this is the ONLY vet that will see her - and he does not see rabbits too often), the vet tested her poop and did a full physical exam. Poop test came back negative for everything and the vet couldn't find anything wrong with her physically. His only guess was its stress, to try a probiotic, and he told us to continue what we are doing and let him know if she doesn't improve. Monday night I bought her a new water bottle(glass instead of plastic), a new water bowl, and the probiotic(which I put on her pellets Monday night). We also left a night light on for her (she sleeps in her cage in our bedroom and we turn all lights out at bedtime, this is nothing new as we have done this since we've had her). Monday night she hardly touched her pellets, vegetables, and hay and still no voluntary water drinking and also not a single ounce of poop or pee. I was able to hand feed her vegetables Tuesday morning 2/7/2023. Throughout the day she did actually drink a tiny bit from her new water bottle, finished her pellets, and ate hay. About midday Tuesday she finally pooped a decent amount and peed a little. Again, throughout this whole process she is acting her normal self, I know bunnies are really good at hiding pain but she has not acted different in any way. We are at a loss of what to do and really need some help, suggestions, anything.
