These are two words which are often used when you're discussing cats. Some people aren't sure how to pronounce these word so I thought I would have a go myself. I made the video a long time ago. It was done very quickly as you can tell and spontaneously. The scientists like to use Latin in taxonomy i.e. the classification of the species. And they like to use Latin when sounding important! "Felidae" refers to the family of cats which are mammals in the taxonomic order called "carnivora". Taxonomy is still slightly unsettled. It has changed a lot because of DNA analysis of the species which is far more precise. Over 100 years ago the classification of the species was all done through observation and even the best scientists got mixed up sometimes. Because one species of cat can look different in different places the scientists thought they were looking at two different species. Some small wild cat species' coats look quite different depending on their location so they can be forgiven for getting mixed up.
Brown gunge. Yes, I know this is a ferret! It does show the build up of dark brown to black ear wax caused by the presence of the cat ear mites in the outer ear canal. This parasite is not restricted to the domestic cat, which makes this photo valid and a useful illustration (I was unable to find a suitable photo of a cat with the condition).

Ear mites (minute crab like creatures) are one of the causes of inflammation of the outer ear canal (scientific term for this inflammation is Otitis externa ). The outer ear canal is the tube that runs from outside to the ear drum (the pathway for the reception of sound), which can be seen when looking at the ear. Otitis externa affects humans and often swimmers as it is called "swimmer's ear" in humans. This YouTube video show ear mites under a microscope. They are not actually in the ear in this video. There are many possible causes of Otitis externa in c
