#estrous

Prynhawn,

There are indeed different British English and American English spellings. Here’s a clarifier:

Estrus: recurring period of sexual receptivity and fertility in many female mammals; heat.

Estrous: American English spelling, the main reproductive cycle of other species females of non-primate vertebrates, for example rats, mice, horses, pig have this form of reproductive cycle. (Also do not confuse with “estrus”, which is a phase of the cycle.)

Oestrous: British English spelling of estrous.

For some reason after the revolutionary war America decided that it needed to spell things differently. Probably just to be difficult. 

Filled with or motivated by estr; fervent.

Filled with, or characterized by, estr; warmly engaged, or ardent, in behalf of an object.

Filled with religious estr.

Full of estr; ardent, fervent; exhibiting enthusiasm or strong passion.

How Often Do Cats Go Into Heat – The Estrous Cycles in Cats Explained

    Unlike female dogs, female cats do not cycle at regular intervals in a year. Cats tend to come into heat depending on the season. The mating season in cats can be determined by a variety of factors, and they range from the length of daylight to whether other cats in heat are present in the environment. If there are 10 hours of daylight available and other conditions are at optimum levels, a…

Naturally, as Sugar is a purebred, her previous owner did not have her spayed. 

About a month after she got to my house, Sugar got in heat. I'd heard from Cat Neighbor that female cats in heat were terrible. She said that when her cat went into heat, it was like hell had unleashed the worst feline demon ever known to Earth. Apparently, Cat Neighbor's cat thought that estrous meant howling like a wild wolf in the middle of the night. Hearing these stories was not uplifting. 

So I was expecting Sugar to suddenly turn into some kind of three-headed monster whose sole objective in life was to destroy my eardrums. Yet Sugar succeeded only in scaring the crap out of me.

The first day, she puked. 

After the puke incident (which wasn't very nice to clean up), everything seemed more relaxed. The only annoying part of having a cat in heat was that she became a highly egocentric animal. It didn't matter what anybody said, Sugar thought it was about her. And any time she heard someone speak, she meowed. Every single time. 

So, basically, this is pretty much how Sugar's kitty period went:

Person A: "Hi!"

Sugar: *Oh it must be a male cat wanting me." "Meow."

*People talking*

Sugar: *nonstop meowing*

It seems that Sugar also confused humans for male cats, as she desperately tried to convince my dad that mating with her was a foolproof decision. 

Anyway, Kitty Period wasn't as scary as heavily-experienced Cat Neighbor made it out to be. We all expected shrill cries throughout the night as Sugar wailed for her prince.
