cycle or cat breeding cycle is the
changing hormones cycle
in the cats’ reproductive system. It is composed of four phases called
proestrus, estrus, diestrus, and anestrus.
The first phase of the feline estrous cycle is the proestrus. Your
queen may be exhibiting her first proestrus behavior as early as four
months of age! So watch out if your queen is beginning to come into heat
(another term for estrus, we’ll get to that soon).
proestrus phase lasts only for a day or two but it is sometimes
unbearable for the owner. This phase is what breeders often refers to
‘calling’. Wanna know why? Your queen won’t go unnoticed
in this period. Here are the common signs of proestrus:
• Excessively friendly
towards men. Yeah, I know. But somehow mamalian hormones are kinda
similar in structure so it can act across species. So your queen may be
just flirting with your men. Or you men. But bear in mind that this
signs usually is obvious towards reserved female.
• Always trying to escape
She will watch for ANY opportunity to dart through open door and almost
escaping. Or she may claw the door demanding
to be let out. Or she might jump at the door knob trying to open the
door herself! These are useful indicators of proestrus if they are not
the usual behavior of your queen.
you can live without this one. She will stand in the window and started
to ‘call’ in a loud vocal ocurring in bursts that’ll build in
crescendo, then dies away. But this depends on the individual,
particularly in different breed. Some queen will all emit but a few
squeaks. Some, (Siamese are famous for this) are so noisy that you and
even your neighbour won’t be able to sleep!
• Rolling, rubbing
will roll around the floor, her behind lifted, rubbing head on
furniture and people. Well, this is kinda normal, but she will do it
more often than usual.
• Strange posture
will assume mating posture when you hold her in the scruff anf pat her
lightly under the tail. Extended licking on her genital area, squatting
with her chest on the floor and her behind lifted up and sometimes her
back feet treading the floor. These are all mating postures.
(or mating) does not occur during this stage. Male cats are certainly
very attracted to queens at this phase but she won’t allow any toms to
mount her. Yet. She’ll usually fold her tail between her hind legs to
In this stage of estrous cycle, will only your queen
accept the stud. This stage can lasts up to ten days if she is not
mated. But if coitus happens, it lasts about 3-4 days. If you allow
your queen to roam about in this phase she might mate with several toms
and conceive kittens sired by different toms.
Cats are induced ovulators. That means your queen
will only ovulate
(release female eggs in her womb) when coitus is accomplished.
Copulation initiates the release of lutenizing hormone (LH) that will
stimulate ovulation. However, the level of LH varies with different
queen and the frequency of the mating. Some queens get sufficient
stimulation by a single mating but others may take several mating to
Estrus terminates shortly after breeding. So to
ensure your success to get your queen pregnant it is wise to leave your
queen and the stud together for as long as she will periodically allow
the stud to mount her.
In the third phase of estrous cycle, diestrus, she
will reject any toms approaching her and her behavior will return to
normal. If she is bred this phase will lasts all throughout the
pregnancy (about nine weeks). But if she’s not bred it will only lasts
about one or two weeks before she went into the next phase.
pregnancy (pseudo-pregnancy) can often occurs if ovulation takes place
without any conception. In this case diestrus will last for about a
month, or six weeks or sometimes longer. The only difference between
this stage and the next is the elevated level of progesterone hormone
in her body.
This is the last phase of the estrous cycle. It is
the resting and recuperative stage that occurs in unmated queen before
the next proestrus starts. This short period of reproductive inactivity
is similar of that spayed female.
During this time their attitude are stable, will
reject any male
advances and their activities are normal. Sometimes you can stretch
this time in your queen by regulating her light exposure. This will be
further explained in fertility management.
