Input: Text: this happened over a year ago, but recently recalled the story and figured you guys might get a kick out of it.

i currently have a brilliantly orange, fluffy fluffy cat. i found the cat in a storm drain when she was a week old, and took her under my wing. initial plan was to get her healthy and find a home, but naturally i grew attached. ultimately, i have my first cat that i've ever owned.

a few weeks fly by since i find the cat, and i figure it's time to commit to a name. friends who have seen the cat, and had cat expertise, addressed her as a girl and helped me come up with a name for her. for some reason, i'd always address her as "cat" or "the cat". must have rolled off the tongue easily. so, i committed to the name catherine.

months pass, and catherine is a massive ball of fluff and hair. quite beautiful and adorable, actually. unfortunately, she was peeing everywhere. "screw the litter box" was what i initially thought she was thinking, but i was also afraid that cat had a urinary infection of some sorts. so i book an appointment with the local vet to check it out, i make it to the vet hospital and i described everything that was going on to the tech. 

as cat and i await the proposed plan, the vet walks in and immediately says "catherine!... what would you say if you found out that you were actually a boy...". i was perplexed - already thoroughly convinced by my cat expert peers that catherine is a girl... lo and behold, the vet instructs me to come take a look as she lifts cats furry furry tail. 

and what do i discover between those furry, furry legs? that i have been living a lie for several several months. i rescued, recuperated, and raised a cat, and i gave the cat an identity crisis. catherine is actually a boy, and was spraying around the apartment to mark his territory of some sorts. 

i took the cat to get neutered because that was what the vet recommended. on the intake form, i was asked to write my pets name.

his name is now mr. peterson.

the end.
