The Dog Neuter Procedure

Neutering is an operation in which both of the testicles are removed.  The operation is usually performed after puberty (after 6 months of age) to allow for complete development of the bone, stature and secondary sex traits of the male.

Health benefits:  Neutering can town down an otherwise boisterous or aggressive male.  Territorial marking instincts can be reduced along with the desire to wander and fight.  Neutering can be beneficial in the prevention of chronic urinary tract disease, testicular and prostate cancer.

Now to see a cat neuter...
The benefits of neutering a male house cat far outweigh any disadvantages.    After neutering, male cats seldom spray urine, the urine loses its skunky odor, and the cat seems contented to stay home more, fight less, and we humans have the assurance that he won't be fathering any more litters!

The antiseptic spray gives the area an orange color.

catneut3.jpg (10133 bytes) The testicle is pulled from the scrotum and the spermatic cord with its blood vessels is in view for the ligating procedure that prevents bleeding.
catneut4.jpg (11248 bytes) A small suture is tied around the spermatic cord and the testicle is removed.  The cord is placed back into the scrotum and an antibiotic is applied to the surgical area.  The scrotal skin closes the incision itself so no skin sutures are needed.  The cat goes home the same day and acts as if nothing ever happened!
