It is probably illegal to sell and buy wild animals in your state. Also you have to consider their habitat and predictors in the area. Cats are notorious for killing rabbits, happens all the time in my area.
You might do what my vet did and it worked. She made a slurry of other rabbits poops and fed it to the one having problems. Basically it reset her system and she was fine after that.
One of mine started that one day and was rolling his one eye.
The vet thought it was a brain tumor but we went ahead and tried the antibiotic and I think something else. He got better the next day and got back to normal. The vet was surprised when I brought min back to be checked, she...
I am a little confused. Rabbits breath through their nose and eat through their mouths. So the nose goes to the lung and mouth to the stomach.
