And don’t forget "Soft kitty, warm kitty, little ball of fur. . . "
You’d think that people would have had enough of silly pet songs. I look around me and I see it isn’t so, oh no. Well, it’s been a while since I posted my best one and it’s Christmassy to boot, so here it is again:
To the tune of Do You Hear What I Hear:
Said the cat to the people everywhere
Do you see what I have?
Underneath my tail, everyone
Do you see what I have?
It’s pink, it’s pink
And it doesn’t stink
‘Cause I wash it with my-y tongue
Yes, I wash it with my-y tongue!
This morning I regaled the dog with this bit of lyric, to the tune of Three Blind Mice:
Who is a pill?
Lil, Lil, Lil
Who will I kill?
Lil, Lil, Lil…
Honestly, I’d have to say I’d think you kind of a nut if you *didn’t *sing to your pets. I mean, that’s what they’re for.
No Clue Boy’s (thanks, Dung Beetle!) song is the only one with custom lyrics I sing frequently to the cats that I can remember off the top of my head. Other ones are “You are my Brixie, my only Brixie” (to “You are my sunshine,” obviously) or “Bellanotte Bellanotte Bella Bella Bell, a Bella Note” (Jingle Bells). I don’t really have any others with lyrics, per se. I do put the cats’ names in most of the songs I sing along too, though. And my husband’s started doing it, too. It’s awesome.
But that gets sung to neurotic physicists, not animals. 
It’s not based on a real song, but I often sing this to my cat:
Who is the kitten in my house?*
His name is Max, he’s really really bad.**
*can be replaced by “in my lap” or “on my feet” or whatever.
**can be replaced by “really really cute” or “really really furry” depending on my mood.
To my dog Boomer:
Boom boom boom let me hear ya say wayoh!
or
Boom! here comes the Boom! ready or not.
To my dog Pepper:
Oh mine Peppar.
Not only does my mum sing to her dog, but the dog will bark along with her and “dance” by spinning round and round in a circle. Hits include “(Poppy is) My Brown Eyed Girl” and “Oh Poppy you’re so fine, you’re so fine you blow my mind. Hey Poppy, hey Poppy!” ( to the tune of the 1980s classic “Hey Mickey!”)
She will occasionally try singing to the other dog, but he just gives her a baffled look.
When I was working at a boarding stables a few years ago, I used to sing to the horses as I was turning them out.
“Mustang Barley” to the tune of “Mustang Sally,” except that Barley hated going out to the pasture and would take his sweet time, so I sing, “Mustang Barley, guess you’d better speed that mustang up…”
I generally sang Aerosmith’s “Walk This Way” when leading the Friesians out because Joe Perry raises Friesians.
And for the Hanovarian named Angel…“I call you Angel of the morning, Angel, I’ll clean you stall out, before I leave…”
There were others, but those are the ones I remember off the top of my head.
I’m a terrible singer and when I sing to my dog I intentionally sing as bad as possible. Usually make up words to what ever earworm I am suffering at the moment.
Ha! 
For some reason that reminds me of this past Saturday night, when I sang to my dog after hearing “Danny Boy” at a piano bar: “Oh Bailey dog, the bones, the bones are calling…from room to room, and 'cross the kitchen floor…”
Of course I sing to the pets, currently all dogs. Jake has a song:
Have a dog
And his name is Jake
He’s the best dog in the world
Have a dog
And his name is Jake
He’s the best dog in the world
He’s the best dog in the world!
Shep has a song:
What’s your first name
Shep, Shep
What’s your second name
Aroni, aroni
Shep-a-roni
Pinky:
What’s your first name
Pinky, Pinky
What’s your second name
Adair, Adair,
Stinky Pinky Adair!
Chiwi (to Flipper’s theme):
They call him Chiwi, Chiwi
King of the weiners
No one you see
is as cheesy as he
And you know Chiwi, Chiwi
Lives in a house with his brothers
Lying there under
under a blankie
Tobey (to Beethoven):
Tober-a-lone
Tober-a-lone
Tober-a-lone
Tober-a-lone
Charlie has no song, but we call him Charlie Bit My Finger.
They all get to hear the the food song at meals:
How do you handle
a hungry dog?
Lots and lots of good dog food
That’s how you handle
a hungry dog.
And more songs as they flit through my head.
I don’t sing songs to my Kitty, but periodically I perform Cat Identification*. This is done by singing the 3 notes of the NBC Chime to the letters C A T, gently poinking the cat with the index finger as follows:
C…left ear
A…right ear
T…nose
- Cat Identification, according to an unimpeachable source, is “clinically proven to be vital to a Cat’s emotional and psychological development. Without the constant reminder of its intrinsic nature the Cat may come to believe that it is a dog, roomba, velociraptor, or communist.”
Aaaaalbert the goofy kitty
Aaaaalbert is awful pretty
He’s the goofedest kind of cat,
Albert the goofy kitty!
I give the cats silly nicknames, so often the songs come out of that. Cuthbert, for some unknown reason, is “The Boopalo.”
If I had my way, I give a kiss to BooPAlo!
He headbutts my hand. I know that he is mine.
Hey, let’s run all over the hou-ou-ouse
Look for a mou-ou-ouse.
Look for a mouse!
Wow, “You Are My Sunshine” is pretty popular. Wonder why.
I don’t remember all of it, though, so my kitty song usually goes, “You are my Tikki, my only Tikki, you make me happy, when skies are grey, oh something something, I don’t know the words, please don’t take my Tikva away.”
ETA: When I was stuck in South Africa for surgery, the worst part was that I wasn’t going to go home to see Tikva for another few weeks. I found myself, in moments of particular stress, singing, My Tikki lies over the ocean, my Tikki lies over the sea… Which was completely literally true.
To the tune of “I’m a little coconut”
"I’m a little gloey-wyrm
watch me wiggle, watch me squirm
give me cuddles, pat my head
Feed me cookies, cheese and bread
I’m a worm, watch me squirm,
I’m glooooooo-ey! "
and for the other dog:
"I’m a little Nenna-bug
Laying on my Nenna-rug,
All I want is Nenna-hugs,
Because i am a cuddle-bug,
I’m a bug, on the rug, Please pet me!
I sing to my son, to my dog, my rabbits… Even the fish. I sing all the time. I have no shame! I especially like making up song about my FARITs (Ferocious Attack Rabbit in Training.) If you’re gonna give something an acronym, you have to some up with a song to explain it!
These just crack me up. With all this inspiration my poor dogs are really in for it.
I already do some nonsense verses for Layla (the jazzy version) and lots of commercial jingles.
Kiiichwa, beggin’ for some cheese Kichwa
Waggin’ can I please Kichwa
Doggie won’t you stop that beagling now
And there’s the Miss Lily/Mr. Gomez song, and the Beagle Walkie Doodle song and a bunch of others. Oh, and the dinnertime song, which is accompanied on the metal food bowls, and sometimes features a drum solo on the overturned water bowl.
I’ve had to restrict myself from singing to them during our walks after I turned the corner one time and came face to face with a stranger who obviously was kind of scared to realize I was walking down the street singing foolishness to my two dogs.
To the “My Favorite Things” song from Sound of Music:
Spoof is our kitty and she’s really fluffy.
Her nose is all pink and her tongue is all roughy.
Sometimes she smells bad but that’s just because
she sleeps in the bathroom on dirty old rugs.
To Tchaikovsky’s Piano Concerto no. 1:
I have a cat. Her name is Winks.
Her name is Winks because she winks.
She winks at me. She winks at you.
Sometimes she blinks, that’s winks times two.
To “Black Betty”:
Crack kitty had a mouse
meow meow meow
Chased it all over the house
meow meow meow
oh-oh crack kitty
I have a couple of folks songs with female heroines whose names I change to Penny when I sing it to the Penny-dog:
Mally Lee:

Oh, and I’ll never forget the day my dad, who didn’t know I was in the next room, came in to find our Dachshund sitting in “his” chair. She (and I) heard this to the tune of Battle Hymn of the Republic: I see the little Doxie and she’s sittin’ in my chair; I leave for just a minute and I find her sittin’ there…
I blame Glee for the most recent pet composition in my house:
[Bruno Mars, “Marry You,” and a big ole hound named Arwen]
She’s a beautiful pup
I’m looking for something dumb to do
Hey Arwen
I think I’m gonna brush you!
Is it the hair on my clothes
or is it your drooly juice
Hey Arwen
I think I’m gonna brush you
