Today I learned my girl cat was actually a boy cat the whole time.
So funny story how this all came to pass. Got my cats as kittens, about 3 months old, who had been born on the street as ferals, rescued, taken to the local feral cat coalition(FCC), where they were given an intial exam/spayed/neutered and given the microchip/vaccine shots, etc. I got 2 and my sister got 2. The FCC designated 1 as a girl cat and 3 as boy cats. I took the girl and one of the boys, my sister took the other 2 boys.
My cats are indoor only. They don't go outside and they don't want to(because it's warm and safe inside and there's plenty of free food so why make life harder?), so they don't get sick. So I basically didn't take them to the vet(yeah, I know, I'm a bad cat dad). Well, in November 2021 one of my kitties stopped eating and I didn't notice until he'd lost a notable amount of weight, partially because I had a lot going on but also because he started doing that thing where he'd go hang out in a corner of an empty room alone most of the time(which should have tipped me off). Long story short: Kitty died of liver failure after not eating, despite me getting cat to eat again(but too late).Tried to get cat to a vet but all the vets are backed up like crazy because Covid and such.
So got my other cat, the girl cat, an appointment for an exam. Took a while, because of the aforementioned vet backup to establish care(lesson learned: Get your pet a vet so you can get them care much faster). Kitty is in good health, but the vet said "Yesh, your girl cat is a boy. Has boy cat parts instead of girl cat parts. He was neutered instead of spayed at that initial exam". The official paperwork from 10 years ago says Female cat, so best we can tell someone made a mistake on the paperwork and wrote "F" instead of "M".
My kid was upset to hear that(4 year olds get upset for weird reasons) but we talked and she understands it's still the same cat. I also told her we're not changing the name and she can call kitty a boy or girl if she wants. Personally, as weird as it is, I'm gonna keep going with "girl" and the same name, despite knowing kitty is male. Kitty don't care. I treat the cat like a cat because as far as I can tell, there's no appreciable difference between a spayed female and a neutered male cat(They both spend 80% of the day sleeping and the other 20% being little weirdos). I also can't tell the difference between male and female cats, I go with what I'm told is the gender, especially if the vet tells me. I looked up how to tell the two genders apart and even with photos I can still barely tell the difference(and it invovles taking close looks at the area just below the butt, which isn't where I want to look if I can help it).
And I wasn't the only one fooled either. My wife, who has known the cat almost as long as I have, never noticed the cat wasn't a girl. Nobody who has met kitty ever noticed(several of which have their own cats). It's not like the cat is going tell me, nor do i think the cat even fucking cares.
