What is wrong with my bunny!?

You can go to the feed store and by powdered antibiotics. Sounds like bunny has a really bad upper respiratory infection. Might not hurt to put him in a real confined space and use a humidifier with a little Vick's in it to help clear him up. Hold him up to your ear and listen to his chest. If it rattles, he needs a vet.

If you elect for the feed store, ask the clerk for rabbit safe antibiotics. Most carry them and they have dosing directions on the package.

I have one word for you VET!!!. Never give any small animal any medications like suggested by the first answer, they all have different medicine needs and what one can take another will die from. A vet is the only one to diagnose what's going on. Call the vet tonight if possible and let them know every symptom and ask for what to until you can be seen tomorrow. With as sick as he seems don't wait until tomorrow night or the next day, go in the morning. A small animal that's not eating or drinking right can drop half their weight over night. I've seen this happen before, some made it, others didn't. This may end up being a severe allergy to a bad infection.

There are a few things to do to prevent some allergies also. Don't use any wood shaving litters like cedar, pine, aspen, etc. all cause reactions in all small animals from toxic fumes when mixed with urine (cedar & pine) to sneezing, watery eyes, hair loss and itching (pine, aspen and other woods). The safest to use is either a paper product litter like Critter Care or Care Fresh, hay, straw (be prepared to go through a lot of hay or straw for they eat it), or like we sometimes do by putting a litter pan with a non wood or non clay litter. We use Rescue Clean Scoop that is biodegradable and has a nice orange scent also very light weight. It runs under $8 at Wal Mart. It's best used with a litter pan with a grate in it since it's so light weight.

I will put it bluntly- Kill it or get to a vet FAST!! your rabbit is exteremly sick- I don't know what from I have never experienced something like this and I kind of hope you don't live near me, be careful and don't cross-contaminate other rabbits just go to the vet!!!!

You need to get that rabbit to the vet ASAP.

These people are diagnosing your rabbit without even seeing it. Get it to a vet and let the professionals deal with getting your bunny better.

good luck

He has a cold and you should take him to the doctor right away. They aren't serious if treated, but can be life-threatening if not treated. Also, if you have other animals, you should keep it away from them until you get treatment for the rabbit.

ONE THING! VET!!!!

Get hold of your veterinarian immediately.
