Why is my 1yr old male neutered cat trying to mount my other male neutered cat?
The most likely cause for any castrated cat to be mounting another castrated cat is due to dominance. I always recommend an exam to assure no health issues could be playing a role in a sudden personality change. If the behavior continues, or worsens and becomes concerning- we can always discuss certain behavioral modifying medications.
