Managing Queens - Breeding

Queens in heat want to be treated like a queen. When pregnant, if you do not treat them like queens they will lose babies. Overall queens are easier than bitches to breed as they are very fertile, but that is the only thing that is easier.

Queens are seasonal poly-estrus, meaning they come into heat repeatedly between Jan and Oct 1st. They often stay in anestrus and will not cycle at all during Oct, Nov, and Dec without the use of artificial light. If you want to keep them cycling year-round you can use lights to maintain 10 hours minimum light per day, and at least 10 hours of darkness.

Heat cycle:

Estrus is usually around seven days but can be as long as 21 or short as three days. If not bred the queen will go out of heat and bring up another set of follicles in waves repeatedly during the breeding season. Time between heats is variable but the average is eight days. If queens ovulate but are not pregnant, they will typically be out of heat for 60-70 days before returning to heat.

Queens in heat exhibit rubbing, rolling and moaning behavior. Occasionally queens will become aggressive and bite during estrus.

Breeding:

Queens ovulate on stimulation of the pelvis and entrance of the penis into the vagina. Males will grasp the queen by the scruff and mount rubbing the pelvis. Queens will typically drop their front ends and raise their rear moving their tail to the side with pelvic pressure or mounting. This posture stimulates the male to breed and if the queen is not ready – she will not allow the male to grasp her by the scruff. Breeding changes happen quickly with anestrus to estrus behavior within 12-24 hours.

Experienced males wait until the queen is ready and do not push it. The male waits until he is allowed to grasp the neck before mounting to breed. Inexperienced males will push their luck and attempt to breed. The female will aggressively repel him. Often this is misread as the female not wanting to mate with the male when the queen is just too early in her cycle for standing heat. All of this behavior insures the follicles are ready to ovulate.

Males:
Males are difficult to evaluate as it’s difficult to know if semen was deposited at copulation. Microscopic vaginal slides made immediately after copulation can confirm presence of sperm. This is a good way to confirm a tomcat is making sperm.

Tomcats that court, mount and breed several times insure ovulation. Ovulation is dependent on pelvic stimulation and copulation with maximum effect achieved with 8 to 12 copulations in a short period of time. Fertility is significantly lower with only 4 copulations. Ovulation should happen within 15 minutes of breeding.

Post Breeding “Yowl” or after reaction:
After breeding the queen screams or yowls. This is followed by vigorously rubbing or rolling on the ground usually from side to side. This is normal behavior and breeders view this behavior as a successful breeding.

After the reaction is past, the female will again solicit the attention of the tomcat. Repetitive breeding will take place.

Female not ovulating:
When a male is of known fertility and female is not coming up pregnant the cause can be lack of ovulation by the queen. Artificial insemination is not common as it is another area where induced ovulation is needed for success.

Shy Submissive Queens:
Dominant queens cause issues in a cattery. If we have a spayed queen that is dominant in a house they will suppress estrus behavior in a submissive queen. Experienced breeders can often miss the heat cycle and if they do catch her in heat, queens are reluctant to elicit the male’s attention resulting in few copulations and missed ovulation. It is best to get these queens away from the aggressive queen, not allowing them to interact or see each other for a time. Always mate the shy queen with an experienced tom and place the queen in the breeding pen by herself for several hours, a few days prior to breeding. Getting the shy queen comfortable and the use of an experienced tomcat that won’t give up easily usually leads to success.

It has been reported that queens will show a preference to one male but this behavior is unusual. Most breeding behavior is designed to attract the male breed, and queens will seek the tom by showing him attention when exposed to him. Rejection of the male may take inducing ovulation by introducing a sterile swab into the vagina and holding the female so the male can breed. This takes a cooperative male and female and I have found holding cats to breed is easier said than done. Be sure to elicit the help of an experienced breeder to help.

Once bred, managing the female like a queen is critical for embryo success. Implantation will happen at day 15. Gestation and management during results in more live kittens at birth.
