Why Is a Male Cat’s Penis Barbed

By Leslie Carver

Male cats who are neutered before 6 months old don’t develop barbs. Male cats who are neutered before 6 months old don’t develop barbs. Every physical characteristic your cat has contributes to survival. The barbs on a male cat’s penis are no exception. They help ensure that his genes are passed on through successful mating. He was not born with them, and if he was neutered very young he may never even develop them.

Cats Aren’t Born with Them.


Male kittens are not born with barbed penises. Mar Vista Animal Medical Center, a veterinary clinic in California, says that cats reach puberty when they are about 6 months old. The barbs develop on the penis at this point because their purpose is to aid in reproduction.

Stimulating Ovulation.

One purpose of the barbs on a cat’s penis is to aid in a female’s ovulation. Females do not ovulate before sexual intercourse. Instead, the barbs stimulate the female cat’s vulva during intercourse, which causes her body to then release an egg. This is painful for the female, but part of the process.

Preventing the Female from Escaping.


The other purpose of the barbs on a cat’s penis is to keep the female cat from escaping before mating is complete. She may attempt to flee because cats are more likely to be loners than dogs and resent the intrusion to some point. Mating is also painful for female cats, both because of the barbs themselves and because the male cat begins by biting the back of the female’s neck.

Early Neutering Prevents Development.


According to Mar Vista Animal Medical Center, male cats who are neutered before they are 6 months old never develop barbs on the penis. Neutering is the removal of the testicles, which stops the cat’s reproductive development. When it is done before the cat reaches puberty, there is no reason for the penis to develop barbs.

Skyndragtigheid en tewe se estrussiklus.

the-1

HONDE SE ESTRUS SIKLUS

Dit kom normaal in nie-gesteriliseerde tewe binne 6 tot 12 weke na estrus voor. Estrus is die gedeelte van die teef se estrussiklus waar sy die reun toelaat om haar te dek, die vulva geswel is en daar ‘n strooikleurige vaginale afskeiding is.

Die tekens van skyndragtigheid kan wissel in intensiteit en kan enige iets van buikuitsetting en vergrote melkkliere met melkproduksie tot nabootsing van baring en soging insluit.

In meeste tewe is skyndragtigheid egter mildelik en hulle herstel sonder enige behandeling binne ‘n paar (1 tot 3) weke. Sekondêre mastitis (inflammasie van die melkklier(e)) kan ontstaan as gevolg van melkstase (die afwesigheid van melkvloei weens die afwesigheid van klein hondjies wat aan die teef drink).

Tekens van mastitis sluit in: warm, rooi, seer en vergrote melkkliere; melk wat dikker as normaal is met ‘n abnormale kleur; koors; aptytverlies; lusteloosheid. Gevalle waar tewe erge tekens toon van skyndragtigheid of waar sekondêre mastitis teenwoordig is, moet die teef na u veearts geneem word vir behandeling.

Daar is verskeie hormoonbehandelings beskikbaar vir skyndragtigheid, maar daar is verskeie newe effekte wat met die behandeling gepaard gaan. In tewe wat dus herhaaldelik erge tekens van skyndragtigheid toon na elke estrus, word sterilisasie aanbeveel.

Gevalle waar tewe erger tekens toon van Skyndragtigheid of waar Sekondere Mastitis teenwoordig is, MOET DIE TEEF na `n Veearts toe geneem word vir behandeling.

  1. Proestrus (9 dae)

Dit is die voorfase van estrus , waar estradiol (sekshormone) konsentreer en vermeerder en die eierselletjies geslagsryp word en die uterus vergroot . Die vaginale wand (vaginale epithelium) vergroot gepaardgaande met diapedesis (witbloedselle of erytrosiete wat die vagina of vulva smeer.

  1. Estrus (9 dae)

Gaan gepaard met die teef se “uitlokking”en vaginale klierafskeidings vermeerder en ovulasie begin. Die siklus word beinvloed deur estrogene en die interval tussen die twee is gewoonlik 7 maande.

  1. Diestrus (70-80 dae)

Gaan gepaard met vroulike “non-mating behaviour”, corpus lutea kom voor (wat ‘n geel afskeiding is) en progesterone uitskei. Uritinêre kliere ondergaan hipertrofie en hyperplasia, vaginale uitskeidings/afskeidings en die serviks sluit in en verklein

  1. Anestrus

Is die verlengde periode van seksuele onaktiwiteit (sexual rest) waar die hele reproduktiewe sisteem onaktief is
