Maybe you could leave out a very shallow water bowl/bowls with only a little water in them? It is important that he can drink if he wants to. Hopefully he’s feeling better now and is less disoriented.

Asfor how much fluids to give him by mouth, its a bit difficult to say. A healthy rabbit needs about 100 ml water per day and kilo body weight. A bun will only drink this much water if it’s diet is all dry food (hay and pellets). Since Buster gets a lot of water in his Emeraid, he isnt on dry food only. You could try and calculate how much water he gets in the recovery formula and then add on some more. Don’t give really cold water, it can make him cold (well, obviously!)

I cant see how often you are told to give him the Emeraid or in how big servings. Its generally considered better to give smaller amounts of syringed food (and water by mouth) more often than a larger amount once or twice per day. This must be weighed against how stressful the feeding sessions seem to be for the bun.

I have never had to use Emeraid, just Oxbow Critical Care. (Emeraid is better for a bun in Buster’s predicament). With CC, the poop will become firm “coco puffs” again once the tummy starts to get back in shape. The poops can still keep being irregular in shape, size, color and frequency for quite some time though, 2 weeks is not uncommon and it can take even longer.

It’s always a bit difficult to decide when to cut back on the support food. Since Buster is tiny, I’d keep the syringe feeding up for some time. Rabbits prefer to eat on their own if they can, so its not like they get lazy and spoilt by being syringe fed. I would assume that he has lost some weight during this ordeal.

The best thing for making sure that a bun gets enough food is to weigh him daily. Vets weigh their in-patients more than once daily. You can weigh him in a bowl on kitchen scales. Make the bowl comfy with a towel or similar. Keep a weight diary, note down date and time of day. Make allowance for the weight of stomach-and bladder content. It’s the quickest way to notice changes that are too subtle for the naked eye.
