SureflapThe SureFlap is a cat flap (sometimes called a "cat door" in the USA) that I have been thinking about. As you might know I have two cats, one very old and one with three legs - I am a kind of cat nurse! I love it though.

They both like to go out into the garden. They never travel more than about 20 yards from the cat flap. I am confident that they are safe.

But, the cat flap is an open invitation to stray cats and what I call time share cats. Time share cats are cats who like to spend time at various homes in the neighborhood. This is probably because they are not completely satisfied with their actually home! That can be for one of several reasons. The most common is because the person is not there much and there is a shortage of food or the food is poor and yours is better.

I have had a few time share cats and one is affecting my quality of life. I call him Marty and he wears a bell. He comes in late in the evening after I have put down night food for my cats. He wants to eat the night food. If he eats it, my little old lady cat wakes me up at 3 in the morning asking (nay..demanding) food. I lose sleep. It is a simple chain reaction of events that messes up my night

The SureFlap recognises the ID chip that is implanted into your cat. I am told that microchipping is quite common in the United States. Microchipping a cat is not completely without health risk, I think it far to say, but it is considered safe.

The SureFlap only lets your microchipped cat pass through the cat flap. At a stroke that would solve the "Marty problem". Another benefit is that it protects the indoor environment of your cats. This is their territory and intruders may cause tensions and even fights. My three legged boy has occasionally attacked or charged at Marty in the home.

There are health risks too if a strange cat eats from your cat's bowl. You don't know about the health of the stray cat. Is she carrying a contagious disease? Will it be transmitted in saliva or through direct contact?

The SureFlap would solve these potentially serious health problems too. They supply internationally (

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
