Update*
After much discussion with the vets and lots of research the cat had his operation yesterday to try to locate the missing testicle and it was a success! Two not one testicles found. One fully grown and the other part formed. No wonder for the past ten years he's been acting like a tom.
He's recovering well and has to have a check-up on Monday. He absolutely hates the cone-of-shame but it is necessary to stop him licking his wound. The worst part is, and cat owners will understand this, he can't wash himself after eating and we all now how long that can take and how important it is in a cat's personal hygiene.
The journey isn't finished yet as there is still a chance that his behaviour won't change as at twelve he is quite old to be neutered but already his urine smells much more pleasant so that's one good result!
The vets are seeing him as an interesting case - it is not so rare to find one testicle undescended but very rare to find two in there. I think they all went into the operating room to have a look.
Let's hope we can put up with the scratching and pitiful miaowing at the spare bedroom door for the next week. He is much calmer if someone is in there with him but being confined is very new to him. We've set a camera up so we can watch without always opening the door to check.
