There is not too much that can go wrong when attempting to determine the sex of kittens, however, I will draw your attention to a couple of important kitten-handling dos and do nots, which shouldbe taken into consideration. Handle your kittens gently. Rest your kittens on a clean towel on their bellies and lift their tails gently to examine their genitals. Where possible, wait to sex kittens until they are over weeks of age.
Make sure that your cat the mother cat is comfortable with you handling her kittens before proceeding to touch them. Put kittens back with their mother immediately if they become distressed from handling. Handle young kittens in a warm area and for no more than minutes at a time so that they do not get cold. Pick kittens up by their tails or hang them by their tails they are not mice! Let kittens spin or twist around on their tails while you are holding their tails this can result in tail fractures.
Handle newborn kittens kittens under 3 weeks of age if you can avoid it. Mother cats especially new mothers can become uncertain of their new kittens if you handle them too much and get your human smell all over them. This can potentially lead to the mother cat rejecting her kittens. Handle kittens if they are still suckling not yet weaned and their mother is clearly distressed by you handling them. Handle newborn kittens Attempt to expose or pull out the penis of prepubescent male cats cats under 6 months of age.
Such animals are not capable of exposing their penis and attempting to do so forcibly can damage the penis. How to distinguish male kittens from female kittens. The best way to determine the sex of male and female kittens is to rest the kittens ontheir bellies on a warm not hot towel, gently lift their tails and examine their genitals. There are several differences that exist between male and female kittens, even newborn kittens, which you can look out for when sexing kittens.
Examine the distance between the kitten's anus and genitals vulva in females and penis in males. Look at the pictures below. These are close-up photographs of the anuses and genitalia of two individual 3-week-old kittens. The first kitten kitten on the left is a young male and the kitten beside it on the right is a young female.
What you will notice from these two images is that the distance between the anus and thepenis of the young male kitten image 1 is a significantly greater distance thanthe distance between the anus and vulva of the young female kitten image 2.
I havelabeled the images below the same images as those above to more clearly illustrate thesedifferences for you. Examine the shape of the kitten's genital opening vulva or penis. These are close-up photos of the genitalia of two individual 3-week-old kittens. The first kitten is a young male and the kitten beside it is a young female. What you will notice from these two images is that the genital opening penis or penis-sheath opening of the young male kitten image 1 is shaped like a small circular dot, whereas thegenital opening vulva of the young female kitten image 2 is shaped like a verticalslit.
I have labeled the images below the same images as those above to more clearly illustrate thesedifferences for you. A bulging scrotal sac should start to become visible in male cats from about weeks of age.
The scrotal sac or scrotum is a bulging out-pouching of skin that contains thetesticles of male cats. It is located between the anus and penis of male kittens and cats. In a newborn male kitten, the testicles are tiny and the scrotal sac barely recognisable e.
If you can see a clearly-definedscrotal sac, the kitten or cat is a male. The scrotal sac is not clearly visible in this 3-week-old male kitten because itstesticles are very small and its scrotum not yet fully developed. This is an image of a week-old kitten who is currently anesthetized prior to beingneutered. To orientate you - the kitten is lying on its back.
You can already see a small, but obvious, bulge between this kitten's anus and penis. This is the scrotum with testicles inside. This kitten is therefore a male. This is a picture of an 8-month-old male cat who is currently anesthetised prior to beingneutered. To orientate you - the tomcat is lying on its back. The scrotum the bit resting upon the pink surgical swabs is well-developed and very obvious with two side-by-side, individual bumps inside it: The penistoo is well-developed and somewhat pendulous.
If you see a cat with these genital features, it is definitely a boy. Kittens or cats with retained or undescended testicles cryptorchid cats will not develop an obviously enlarged or pendulous scrotum. Testicles should be palpable in the male scrotum from the time of birth.
The testicles of male kittens descend into the scrotal sac just prior tothe kitten being born. It is therefore possible for testicles to be palpated in thescrotal sac regions of very young male kittens, even if the scrotum sac itself has not yet obviouslyenlarged.
For example, testes were clearly palpatable in the scrotal region ofthe three-week-old male kitten pictured above, even though no scrotum could be seen. To feel for testicles: If the kitten is a male, what you should feel between your fingers are two smooth, ovoid, small approx mm diameter in a 3-week old kitten objects located side-by-side underneath the skin of the scrotal sac region. These are the testicles.
Often you'll only feel these testicles one at a time it is hard to grab bothat once in a small male kitten and often these testes will deftly slide away from your finger-tips when pressed they are tricky to grasp hold of and feel like small peas rolling away under your fingers. This pic shows where to palpate for testicles in a male kitten or cat. You may not be able to feel the testicles of kittens or cats with retained or undescended testicles cryptorchid cats because their testicles will belocated ahead of the scrotum, perhaps even within the cat's abdomen.
Colour can be your guide. Occasionally, the fur color of your cat or kitten can give you some indicationas to the sex of the kitten. Tortoiseshell cats cats with three colours - white, black and orange are almost always female.
Ginger cats are predominantly male, but can sometimes be female. Ginger is a less-reliablecolour indicator of feline sex.
