How to Tell if Your Female Cat is in Heat

Female cats that are not spayed will eventually come into heat
(technically called oestrus), and the signs are obvious, once
you know what to look for.  Immediately preceding oestrus, your
female cat may become unusually affectionate, sidling up and
rubbing her hind quarters against furniture, stuffed toys, other
cats, and/or her favorite human.  She may spend excessive
time licking her genital area.  

(Note: Lacking the other behavioral traits on this list, genital
licking can be a symptom of a urinary tract disorder, which can
be serious if not treated promptly.)

Signs that a female cat is in heat:

1.    She will vocalize loudly.  This “calling” may go on for
several days, unless she mates.

2.    She will assume a mating position: head down, forelegs
bent, rear quarters raised to expose the perineum, with the tail
raised and held to the side of the body.  Her rear legs will tread
rhythmically, as if walking in place.  

3.    She may also spray vertical surfaces with a strongly
scented fluid by backing up to the surface and raising her tail
high.  The tail may quiver, and she may perform the rhythmic
treading described in the step above.   

4.    If your female cat does not mate, she will go into oestrus as
often as every two to three weeks for several months each
year, until she either mates or is spayed.

Your female cat should be spayed as early as possible.  
Female cats as young as four months can go into oestrus.  It
will not only cease the uncomfortable heat cycles, but it will also
prevent certain serious medical problems.  

Your veterinarian may be able to give your female cat
hormones to stop the oestrus, if spaying is not immediately
possible.
