What should you check for when inspecting the ears of a rabbit?

When inspecting the ears of a rabbit, it is crucial to check for mites and canker because these conditions can lead to significant health issues. Mites, which are tiny parasitic insects, can cause irritation, inflammation, and excessive scratching, leading to injuries or infections. Canker, often referred to as ear canker or ear infection, can result in a buildup of wax, debris, or even pus in the ear canal, which may indicate an underlying infection or parasite infestation. Recognizing these issues early can aid in timely treatment and ensure the rabbit's overall health and well-being.

The other aspects, such as color and length, weight and size, or fur texture and thickness, while potentially important in general rabbit care, do not directly relate to the specific health conditions that can affect the ears and are, therefore, less critical during an ear inspection.
