The following are all things that have worked well in our rabbitry.
Feed your rabbit only plain rabbit pellets with no seeds or nuts. NO greens should be given until bunny is 6 months old. A young rabbit has a very tender stomach. Changes in its diet can give it diarrhea which can kill it. If bunny's bottom does get dirty, put his bottom under running water and maybe use a little soap, and he will clean right up. Feeding hay may alleviate the diarrhea.
Provide your rabbit fresh food every day. If the food is left in the feeder for an extended period of time, it will absorb moisture and turn sour. Eating this will give your rabbit diarrhea. Hay is a NECESSARY daily part of a rabbit's diet.
Your rabbit will chew on anything. Use food and water bowls made of metal or ceramic. Do NOT put anything in his cage like towels, blankets, etc.
We do not recommend a wooden cage for your rabbit. It is hard to keep clean, thus making it a breeding place for harmful bacteria. Your rabbit will chew on the cage and may injure its mouth or possibly escape. Rabbits need good air circulation to prevent respiratory illness.
Red urine is your rabbit's way of getting rid of extra copper. No change in diet is necessary.
Do NOT bed your rabbit in wood chips. The bunny may eat the chips instead of its food and starve to death or it may have stomach trouble. Do NOT use cedar chips near bunny.
High humidity and temperatures can quickly kill a rabbit. Warning signs: red tinged ears or a wet mouth and chin. Placing a frozen two liter drink bottle in the cage with the rabbit can help keep it cool.
Bunny's toenails will need to be clipped. Bunny will also need to be wormed using the same wormer that you would use for a dog or a cat.
