Writing this to see if maybe someone on here has had a similar experience. Dumbo is my biggest of four New Zealand whites. He is a neutered male of great health, energy and appetite. A few months ago i noticed him leaking a brown liquid (not mushy cecotropes, similar in color and consistency to dark coffee) (also not pee, it has a foul odor like poop) as he hopped across the room one morning and noticed he was covered with it underneath. immediately i cut pellet consumption and put him on a strict hay only diet until i could get him to a vet. After i cleaned his mess and wiped his butt as best as i could, he immediately hit the hay and was pooping big brown healthy looking pellets. Strange…Vet checks him out a few days later, he had not episode since and had done a great job of cleaning himself up. Vet schedules for blood work and a fecel sample. Blood work done, all is good, nothing abnormal. He ends up having this a few more times as i weened pellets back in and also had it one time when i gave him a timothy hay cube to chew one. (im assuming this was due to food) Fecel sample took some time because the liquid would only happen late at night and would dry by morning. The one night around midnight, he does it, i rush and grab a good size sample and bring it to the vet the next morning. Fecel sample comes back perfect. No coccidia, no parasites. Im stumped, as are both my vets that see him. In the mean time, ZERO loss for appetite, ZERO energy loss. A perfect, but stinky bunny. Also he had even managed to gain a pound during visits!
After cutting pellets (oxbow adult rabbit pellets) entirely from his diet, i introduced greens. Especially dandelion greens, chiccory, escarole, endive, raddiccio, mint, dill, kale (sometimes), parsley (sometimes) and so one. What i noticed was he no longer was having the liquid droppings. Also his energy which was great, really went through the roof. I figured this was clearly a carbohydrate/sugar issue and we have figured it out. We went a solid month with no issue up until this week. Still consistent with his salads in the morning and night, measured for body weight (now over 9lbs up from 8 ) and a fantastic appetite for hay. Just this past weekend, This all happens again. I cut out the greens and put him on hay strictly. Good for one night and last night was even more than i have seen him have before. I am completely stumped now. His diet is impeccable. Zero pellets, zero junk. Timothy Hay from Small Pet Select as well as fresh greens, thoroughly washed by myself. Occasional 1″ slice of banana or a single strawberry with stem but never more. His appetite is there, his energy is there. I just do not know where to go next. I have searched online and i find some things but every is quick to point to diarrhea or cecotropes but he poops normal and produces normal cecotropes as well. He will do this and then poop 12 hours straight of perfectly large, healthy light brown hay poo balls. Any one with similar experiences? Any insight would be great.
