I don't think it's as rare as you say. I've found it very common here in NZ.

Monorchidism - Anyone?

I don't think it's very rare either. Here in the Netherlands you have to send in a statement from your vet with the application for a pedigree that the father of the litter has two descended testicles, and toms who are cryptoorch will be disqualified at shows.
The mother of my Birman had a monorchidic boy in her first litter, he's from her second litter and one of his testicles didn't descend until he was six months, we were kind of worried that he had inherited this condition too, as they would've had to open him up and go looking for the missing testicle during his castration if it hadn't descended.

Ok here's what Susan Little DVM, diplomate ABVP says:
Cryptorchidism refers to the failure of one or both of the testicles to descend into the scrotum and remain there by 7 to 8 months of age. While Unilateral cryptorchidism is most common, it can be bilateral. The mode of inheritance is suggested to be recessive and polygenic, and cryptorchid males should not be used for breeding. Unilateral cryptorchid males may be fertile and also should be casterated.
Is it an inherited trait?
Cryptorchidism is an example of a sex-linked trait. The trait is physically expressed only in the male even though it can be carried by females. Both the sire and dam of an affected cat should be considered to be carriers. A reduction in the number of cryptorchid cats in a breeding program can be achieved by removing the affected males and carrier parents from breeding . If the problem is widespread in the family line full siblings of an affected cat should be eliminated ffrom the breeding program.
How common Is It?THe rate of cryptorchidism in cats was 3.8%, most commonly represented breeds included the himalayan (6%) and Siamese (4%) DSH cats representeed 50% and DLH cats (6%).Most crytorchids were unilaterally represented (90%). and of thsoe cats the left and right sides were equal.

Oh,and 49% of the time the testicle is in the groin and 33% in the abdomen. 14% within the inguinal ring.

Wow, that is great information! Thank you SO much!!
Our CH boy Arthur is monorchid. The vet thought he was cryptorchid at the time of his planned neutering, but try as they might, they could not find the missing testicle!
The final consensus was that he only has one, but the vet was reluctant to proceed with the neuter "just in case" it could ever be found on ultrasound, so that the next vet would know which was the missing one. So my poor little man only has one, and it's gotten big enough to fill the space where two normally go!
Wonder if there is any connection between monorchidism and cerebellar hypoplasia?

My very first pet Ragdoll was bilateral cryptorchid. They refused to do the surgery until 9 months of age, to give the testicles time to drop on their own. The surgery went fine, they told us they found both in the upper abdomen and removed both. He is almost 7 now.
His entire behavior has changed since the surgery. I don't really believe it has anything to do with the removal of the testicles. He doesn't eat well, his coat stays in dull shape, he is very moody and temperamental, and doesn't like anyone except my husband. We have taken him to 2 vets, they have ran tests to find if there is anything to explain his "depression". They have tried different meds, and nothing has worked. The 2 vets suggested putting him down, but we couldn't do it. We let him live with my Dad, he doesn't have any pets, so we thought he would get lots of love and attention, but his behavior got worse, so we brought him back here. We have to keep his nails trimmed more, to prevent him from scratching us or other animals. He mostly likes to stay away from everyone, but will come around every once in awhile for a little bit of love from my husband.
I continue to wonder if his behavior had anything to do with the bilateral cryptorchidism, but I have never found any research that would point to it.
Has anyone had a similar experience in behavior?

Family,
I never heard of that before - sorry about your kitty. IMO I don't think it has anything to do with the neutering. The dull coat would indicate other problems to begin with. Has a complete blood workup ever been done?
Seems odd that his behavior changed so much and not for the better - you would think the opposite.

Yes, they did a complete blood work up, but would not do a thyroid panel, as the vet kept saying and continues saying it is rare and he isn't old enough to have thyroid issues. The behavior, coat condition, weight, all has seemed to point to a possible thyroid problem.
I also really don't think it has anything to do with the cryptorchidism. I also called the vet a couple of years later, just to confirm that both testicles were found, as I thought maybe they missed one.
We have learned how to cope with him, the kids and cats have all seemed to learn to leave him alone. He sleeps most of the time, and get up to find a different spot if that area of the house gets to crowded for him. We have to watch his body language, as he will get agitated for no reason that we have found, and will go into attack mode. He has tore me up a few times, and got the vet a year ago with several bites and scratches. He has to be wrapped in a towel at the vet to be treated.
They have also listened to his heart, and it is fine.
I would be welcome to any suggestions.
Thanks!!

I don't think there is a connection. My CH boy definitely had two testicles and I have never heard of another cryptorchid CH kitty. Cryptorchidism is not uncommon so it's probably just a random coincidence.Originally Posted by Mom of 10 Cats

I don't understand why the vet wouldn't want to take out the one descended testicle. S/he can just write in his record whether they removed the right or left testicle. If one is taking up the entire scrotum anyway it's not going to be easy to visually tell whether it's the left or right to begin with. Plus if his urine loses the "tomcat" smell, then you'll be able to tell that he probably only had one testicle.
