Cat's Canine Teeth

As the cat has a shortened face there is also a shortened jaw with less space for teeth and as a consequence cats have fewer teeth than other carnivores; usually 28 or 30 compared with 42 for dogs and bears.

A cat's teeth are specialised for different tasks.  There are the incisors which are the small teeth at the front of the mouth, used for holding and nibbling (you will see a cat nibbling his fur when grooming).

There are the rear molars which move against each other like the blades of scissors for slicing and cutting.  Then there are the large strong and somewhat flattened canines (the fangs you see on either side of the front of the upper jaw) which are used for stabbing and delivering the killing bite usually to the nape of the neck of small prey if we are talking about the domestic cat.

It is said that the cat's canine teeth fit between the neck vertebrae of prey like a "key in a lock" (Paul Leyhausen).

It has also been suggested that the canine teeth of the cat can feel like the fingers of a hand due to the conglomeration of nerves at the base of the teeth.  This allows cats to feel for the gap between the prey's vertebrae before biting and severing the spinal column thereby killing the prey.

The canine teeth of the cat forces the vertebrae in the neck of prey apart a bit like a wedge being hammered into a gap.  This breaks the spinal-cord.

Cat Ear Mites

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). Photo Stacy Lynn Baum under a creative commons license. 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

Feline Mange

I'll write about three types of feline mange (a) feline scabies or head mange (b) demodectic mange and (c) sarcoptic mange. The source material is from Cat Owner's Home Veterinary Handbook - the best on the market . Generalised feline mange? Puerto Rico - Photo by Gotham City Lost And Found Feline Scabies - head mange Head mange or feline scabies, is a fairly rare condition in cats, which is caused by the Notoedres mite (head mite) that only reproduces on cats. The female mites burrow a few millimeters (that is a lot) into the skin around the head, and neck to lay eggs, which hatch and lay their own eggs. Their presence and activities causes intense itching that in turn causes the cat to scratch. The scratching will obviously be noticed and it will cause the skin to become red, scratched and worse infected. Symptoms: hair loss and scabs, thick wrinkled skin and grey/yellow crusts form plus the symptoms of scratching. Feline mange (head mange) is contagious and tr

Cat Anatomy

Cat Anatomy - Photo by Curious Expeditions . The picture above was taken at Wax Anatomical Models at La Specola in Florence, Italy. The photograph is published under a creative commons license kindly granted by the photographer. I am sorry if it is a bit gruesome. It is pretty well all I could find as an illustration that was licensed for publication. Cat Anatomy is a very wide ranging subject. The anatomy of a cat is very similar to human anatomy. If you were writing a biology book for students of biology you would go through every part of the a cat's anatomy in some detail. It would be similar to writing a book about the human anatomy. It would be a thick book and pretty boring for your average internet surfer. So, how do you limit such a big subject and make this post meaningful? The answer I think lies in doing two things: Having a quick general look at cat anatomy - an overview and; Focusing on the areas of cat anatomy that are particular to the cat and of parti
