sick rabbits

Question
I had bought two 5 week old rabbits a week and a half ago. One of them died four days after I got it. It had diarria and started having seizures. The second one died yesturday and it had also got diarria. Now starting tonight my other rabbit that is 5 months old and possibly pregnant has diarria. Whatever the other two had when I bought them transefered to my other rabbits. I also have another 5 month old and twelve week old rabbits. How do I stop the diarria so that nothing happens to my female and how do i keep the other two from getting it? Whatever they have is killing my rabbits.

Hi Chasity

Sorry to hear you have sick rabbits. The first thing that came into my head was coccidiosis, which is highly contagious and pretty nasty. I recommend you get all your remaining rabbits to your vet ASAP. They need to be tested to see if it is cocci or something else and likely need gut probiotics and antibiotics to fight whatever it is those two babies brought in. You can read about cocci here:

I am also concerned someone was willing to sell 5 week old rabbits, they are not weaned until 8 weeks and at 5 weeks should still be with mum. Being weaned too early leaves their still developing immune system open to infections and parasites and they are more likely to get sick. Just the stress of being moved from mum so early can kill them. Mucoid enteritis is another killer of baby bunnies but not so contagious as cocci.

Good luck at the vets!
