  • Perform a thorough physical examination, and establish a comprehensive minimum data base. FeLV Feline leukemia virus disease, FIV Feline immunodeficiency virus disease and other viral infections and bacterial infections can reduce fertility.
  • The male may have a low libido. This can arise as result of aggression by the queen Failure to accept male at breeding, and he may require more time to settle. Overuse of the male may also decrease libido, as well as semen quality and conception rate. A mature male can be used 3 times per week, or for up to 5 consecutive days followed by a rest period.

  • Physical problems may arise as a result of an inexperienced male, matted hair around the penis and/or vulva, and great discrepancies in size.
  • The male should also be free of obvious potentially heritable defects, especially conformational defects. The veterinarian's role in this respect has to be informative and not judgemental; great diplomacy will be required in some cases.
