I call it 'Ode to the late Hermione', written to the tune of Ode to joy:

Stinker pooper farter tooter,
Smelly butt and rotten arse,
If you weren't such a cuter,
We would send your butt to Mars.

NASA would be ove-erjoyed with,
Geoforming going well. Ooooh,
How can such a little kitty,
Make Mars smell like rotten hell.

Stinker pooper farter tooter,
Smelly butt and rotten arse,
If you weren't such a cuter,
We would send your butt to Mars.

But be careful, don't light fires,
Her farts are quite flammable,
Turning Mars into a pyre,
Stinking gas cloud pole to pole.

I have many sayings for my cat and my dog but haven't made any songs. I have sung other songs others have made to them. Typically my cat is the making songs. She sings a sad ballad when she thinks she's home alone as she carries her toy until she finds us.

Long cat

Long cat

He is long

And is a cat

Long cat

Disclosure: my wife is the singer songwriter in the house so this is technically her's

Who's my precious little

Tiny baby boy?

Who's my tiny little

Precious baby boy

Baby boy?

The exact melody and lyrics vary, but it's always in the Dorian mode with lots of little arpeggios. And always sung with an operatic voice, with the "r" in "precious" heavily rolled

A sort of country blues song about how my cat would ignore my friend until they went into the bathroom to poop, and then the cat was all about hanging out and being affectionate.

"You only love me when I'm pooping.."

Usually just Kiiiittttyyyyy sung like an opera over and over. Maybe with some Italian sounding noises thrown in.

Hey there, chonky boi Sitting at your bowl so hungrily

Sung to the tune of The Howdy Doodie Theme, which I have never seen a single episode of:

🎵🎶 IT'S BREKY-BREAKFAST TIME🎶 🎵

🎵🎶 IT'S BREKY-BREAKFAST TIME🎶 🎵

🎵🎶 IT'S BREKY-BREAKFAST TIME🎶 🎵

🎵🎶 IT'S BREKY-BREAKFAST TIME🎶 🎵

Repeat as long as I am filling their bowls.

Isabella Bizzy Boo

she's a kitty, yes you do

she is grey and furry too

she's an Izzy Bizzy Boo

Fat bois
You beautiful phat bois
You can't lick your back
You can't lick your bum
Because you're a beautiful phat boi

Cat who is a kitten,
Kitten who's a cat.
Cat who is a kitten who's a cat, cat, cat.
Imagine that! A kitten who's a cat!

Pussy pussy pusskins You're still my friend Despite all my sins Pussy pussy pusskins I nibble your toes beans And risk toxoplasmosis Because I looooooove yooooouuuu!

Cat looks at me like I've had a stroke and demands either a head scratch or human tuna

To the tune of Industry Baby:

He is a Babyman A stimkin man And sometimes he's a chimkin man. He's begging on his knees Mommy please Won't you give me zoppity"

He's a Sphynx. His name is Babyman, he's stinky, and when he acts a fool we call him Chimkin Man because he looks like an uncooked chicken flailing around the house.

Zoppity is his freeze-dried venison food, named after a reference from The Office. "Bippity boppity, give me the zoppity."

Jezz, Jezz, Jezz,

Jezz, Jezz, Jezz,

Shake your Jezzie,

Shake your Jezzie! 🎶

(Her name is Jezebel, and I'm not very creative, lol)

Sing in generic high pitched baby cat voice with a lilt to it.

Looking for Leonard, Hey! Dirty!, Rudy Patootie, Just a good ol’ boy

Those are some with “titles,” but there are infinite spontaneous songs that only exist for a few minutes.

Whenever they beg for food outside of feeding time and loiter at the food area, i start singing "you still belong to meeeeeee" over and over while i follow them and gradually get more and more invasive of their personal space until they scamper off

You mean you're only supposed to have one???

...I have a certain pop song stuck in my head at the moment, so I was singing Pink Spooky Club to my cat earlier.

"They call her Maya", to the tune of the 1960s Flipper theme, with improvised lyrics mostly on the topic of prettiness, cuddlyness, and diva nature.

Started as a song about her brother Tigger, on the topic of handsomeness, food motivation, and mischievousness. Sadly Tigger passed away recently :(

yo cat, you want some fat pellets?
