Hello All, just thought I would add a bit more to this thread, as I have just had a Rex buck that knocked on deaths door and he pulled through. If I had left him in his cage he would surely have died during the night, and I was sure he died in my arms twice during the night, but thankfully he started going again. Yes, he was at the point where he couldn't hold his head up, limp and just like a dead weight, not strong enough to swallow for the most part. Eyes were glazed and alternate between closed and staring and at the point when I thought he'd gone, he blinked.
Here's what I syringe fed him during the night and he's on the mend now:
-Electrolyte drink:
1/8 tsp bicarbonate of soda
1/8 tsp salt
1/2 Tablespoon Molasses
1/2 cup of hot water.
Try to feed this within a 24 hour window, but if you can get it into them in 12 hours all the better.
Baby food smooth (recommended for a 4month old human child). Flavours recommended: pear & banana, or Sweet Potato & carrot.
V8 Vegetable juice - not sure if this is something localised to my country, but it is a 3-veg juice, made by the companies that make dried stock powder / stock cubes. Literally vege juice made from tomato, carrot and celery, has no sweeteners.
Feed all of these warmed, stand in a cup of hot water to warm through. Will need to syringe these all in, depending on how sick your bunny is - if it is your first time syringe feeding, poke the syringe into the back of mouth, between the back teeth and front teeth, literally nearly at the start of the throat.
I believe it was hypothermia that he's had, as he has shed his winter coat and is growing his summer one, because we had a warm patch and now it has turned frigid again.
