Vanodine

You can use vanodine as a disinfectant spray, directly in water bottles as a preventative, or even in a fogger for airborne illness! A single bottle is not very expensive and it goes a long way. It covers most of the more common rabbit illnesses.

Pros: kills a wide variety of organisms that cause rabbit illness, a little goes a long way, can be used in several ways

Cons: hard to find in the city, often have to order it

Excellent for all around sanitation around your rabbits. Cages, dishes, all can be kept in good condition by using Vanodine. Expensive, but worth it, IMO.

Pros: Good for cage cleaning

Cons: none
