Just a suggestion since we had a male with the same symptoms. We found that
he had a urinary tract infection which he was misinterpreting as a sexual
urge. Of course, this could also be an incomplete neuter (one testicle not
removed), but you might try your vet's choice of anitibiotics first, before
thinking about surgery. I am not a vet. I am a vet tech, running a ferret
shelter.
