Reminds me of a class mate who learned to keep their mouth shut while performing EEJ in rams in the worst possible way. Pretty funny incident for all those not involved though.

No - it was meant in jest. Sheep bottom sized.

Seriously? I'm assuming Michael's EEJ isn't made for cats to begin with...

And why should you get in to any trouble with anyone?

[quote user="James Laidlaw"]Thanks, that's not far off what I've read. Up to 7 weeks still fertile too.

We have an electeroejaculator. I will post it to you at my own expense so long as you post a video of you testing the cat.

To be sure - you understand.

No experience I'm afraid.

Found this:

"Surgical vasectomy involves bilateral removal or occlusion of the portion of the ductus deferens, rendering the animal infertile by preventing sperm from being ejaculated during copulation [51] and [52]. However, undesirable male sex characteristics and behaviors, as well as androgen-dependent diseases, are not prevented, since androgens are still produced [51]. Vasectomy of dominant males has been suggested as a method of feral cat population control since vasectomized dominant tom cats will prevent submissive, intact toms from inseminating non-spayed females [53].

In both the dog and the cat, vasectomy may be performed through a 1- to 2-cm incision located in the inguinal areas of the dog and cranial to the scrotum (genitalia) in cats [51] and [52]. Following skin and subcutaneous incision, the spermatic cords are identified, separated, and exteriorized from the tunic using a combination of blunt and sharp dissection. Gentle caudal traction and manipulation of the testicle can be helpful in identifying the spermatic cord and ductus deferens. Following isolation of the ductus deferens, a segment of the ductus is then removed and both of the severed ends of the ductus ligated. It has also been reported that vasectomy may be performed intraabdominally via laparoscopy with occlusion of a segment of ductus using bipolar forceps and electrocoagulation [54]. Vasectomy in the dog has also been described using a Vasocclude clip applying device through a small scrotal puncture site [55]. In this study, 99.9% of sperm were absent within 1 d after vas occlusion. Other studies have reported azoospermia in the dog following bilateral vasectomy to develop from 2 to 21 d, whereas in cats, live sperm have been identified for up to 49 d following prescrotal vasectomy [54], [55], [56], [57] and [58]."

I was going to ask the same question, why?

When I did a spell of voluntary work in Greece I was often asked to vasectomise cats rather than castrate them, but I refused and castrated them. Their reason was "I want him to have his fun"

I would have done the same...but playing devils advocate, would performing a vasectomy lead to a decrease in the stray population? Presuming you're not going to manage to spay all queens, some of these would get mated by the vasectomised cats, have induced ovulation, but not get pregnant....I suppose you would need a large proportion of vasectomised cf. entire for this to work very well...

Complicated story, client in tomorrow so haven't yet discussed. Going to have consult first and would rather not do, but would like to hear if anyone has done one.

Why would you/the owner want to do this? Are spraying, fighting and straying, which he would continiue to do, not the main reasons for castrations? I've never done it, but I don't think it would be too difficult to do.
