Feline Gestation Period

The feline gestation period is the length of time from conception to birth. Conception could be defined as the moment embryonic life begins by the formation of a viable embryo (zygote) through the coming together of the male sperm and female ovum or egg.

The feline gestation period averages 65 days with the range extending from 63 to 69 days all of which are normal. Apparently the gestation period of Siamese cats may be longer at 71 days.

If the kitten is born prematurely before 60 days of gestation the kitten is unlikely to survive.

It may be difficult to tell if our cat is pregnant. Cat breeders of course will have all the knowledge gained from experience to tell. I have a web page on cat pregnancy which expands this page considerably.

Pregnancy testing?

My research indicates that at the time of this post there is no equivalent of a pregnancy test (wrong? - please leave a comment). However at:

---17-25 days veterinarian may be able to feel the kitten (feeling the inside of cat from the outside is called "palpation"). This clearly must be done with care and experience (veterinarian only I would suggest) as it can damage the embryo.

---20 days the heartbeat can be detected

---22-25 days (Drs Carlson and Giffin say it can detect pregnancy as early as 15 days) ultrasound can be used to check pregnancy.

---30-35 days a blood test can confirm pregnancy.

---43-45 days an X Ray can tell how many kittens are in the womb as the skeletons would have formed.

Signs during of pregnancy:

---slight gain in weight

---sometimes there is morning sickness at 3rd to 4th week lasting for 3-4 days. This is due to hormones and distention of the uterus

---pink nipples (35 days)

---near birth - enlarged breasts and milky fluid may come from the nipples.

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
