Failure to accept male at breeding

ISSN 2398-2950

Contributor(s) :


Introduction

  • Probably rare in cats when not observed, but a problem when observed closely.
  • Cause: psychological (dominance, poor socialization), physiological (immature, wrong stage of estrus), pathological (pelvic canal abnormalities   →   pain, physical barrier).
  • Signs: fear/aggression in presence of male, refusal to submit to mounting.
  • Treatment: depends on cause - artificial insemination, sedation, surgical correction.

Presenting signs

  • Queen does not allow male to mount at first or subsequent attempts.
  • Aggression towards male.
  • Fear of male.

Age predisposition

  • Young.

Cost considerations

  • Artificial insemination.

Pathogenesis

Etiology

Psychological

  • Sire preference seems to occur occasionally.
  • Traveling to stud may upset timid queens and inhibit estrus.
  • Some males will not mate away from their home territory.

Pathological

  • Previous trauma to pelvic canal.

Physiological

  • Immaturity.
  • Not in estrus.

Predisposing factors

General

  • Poor socialization.
  • Pelvic trauma.

Diagnosis

Client history

  • Refusal of male.
  • Signs of pain on first attempt at intromission.

Diagnostic investigation

Other

  • Vaginal cytology: to determine stage of estrous cycle.
    Collection of vaginal cells for cytology may stimulate premature ovulation.
  • Cytology is an excellent tool for determination of follicular development and when to mate.
  • When cytology is cornified  Cytology: vaginal cytology from a queen in estrus , there is substantial follicular development. This is a good time to mate the cats.
  • Vaginal cytology changes shortly after ovulation to mainly non-cornified cells  Cytology: vaginal cytology from diestrus queen .

Radiography

Other

  • Endoscopy: Need a small endoscope.
  • Difficult in cats.
    Most information is gained during the withdrawal of the endoscope rather than during insertion.

Confirmation of diagnosis

Discriminatory diagnostic features

  • History.
  • Clinical signs.
  • Vaginal cytology.

Definitive diagnostic features

  • Radiography.
  • Endoscopy.

Treatment

Standard treatment

Prevention

Control

  • Breed to alternative male.
  • Adequate socialization.
  • Move queen to stud early to allow time for acclimatization.
