Domestic Cat Kills 16 Animals a Year

The domestic cat kills 16 animals a year, so say research scientists at University of Reading, UK. As there are an estimated 626 domestic cats per square kilometer that makes 626 times 16 animals killed by cats every square kilometer per year. The figure is 10,016. This translates to 92 million animals a year, of which 27 million are birds so the researchers say. How accurate is it?

There are some estimates and uncertainties (to me) in this:
  • the figure of 16 per cat is estimated
  • the figure of 626 cats per square kilometer seems to be estimated
  • these estimates are based on the area around Reading, how typical is the area?
  • Does the research differentiate between domestic cat and feral cat?
  • the researchers say there are 9 million domestic cats in Britain. I don't know how accurate this figure is or how it was arrived at.
There has been a constant argument about the impact of the cat on native wild life none more so than in Australia, where the feral cat is persecuted for killing native wildlife (once again on the basis of disputable analysis). See Savannah cat ban and feral cats of Australia, for example.

The next job for the researchers is to track the cats over their territory using GPS devices to see how far they roam. This research, as I understand it, relates to "family pets" or a better description would be companion cats. If that is the case the figures would be very different in the United States as the majority of domestic cats in that country are full-time indoor cats.

Er, um, what did you guys say the domestic cat was doing to wildlife?

It was felt after the research that the domestic cat was responsible, at least in part, for the 60% decline in the sparrow in Britain since the 1980s. I am not sure that this research will finally clear up the argument of the domestic cat's impact on native species. The biggest factor for declines in wild life will certainly be from our activities. This was taken into account by the researchers in making estimates but I wonder how accurate they are when they say that the domestic cat kills 16 animals a year?

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
