Neutured cat
case101 posted:
I have a male cat that was neutured about 1 or 2 month's ago, he is spraying on thing's in the house as well as chasing the female cat whom he fathered a litter of kitten with, should this be happening? We were told that he only had one testicle but that there could be another one up inside. Could this be the reason for his behavior?
Ponyrun2 responded:
Ask your vet if they searched for the 2nd testicle... if it is retained inside the body it could cause cancer problems in the future.... if your were told there could have been a retained testicle I would have asked why it wasn't removed as well (granted it's a more invasive and costly surgery than just a simple neutering)....

I'm not sure but I would think while a retained testicle might not produce viable sperm it certainly could still produce testosterone which is probably what's behind his behavior... but it could also be related to his age... the older they are when neutered the more likely it's "habit" rather than hormonal behavior...

I had a male dog neutered before he started "lifting" his leg and he never did... another male dog was neutered after he started lifting his leg and continued to do so....
Bonnie Beaver, BS, DVM, MS responded:
Internal testicles are a major source of testosterone and testosterone is the primary hormone responsible for the behaviors you are describing. The behaviors can be seen in castrated male cats (about 10% of them) but when you said that only one testicle was removed, it is a STRONG indicator that there is another testicle still present. It needs to be removed.

The cat in question is about a year old.
