He is presently called 'Don Corleone -Garfield', because he acts like a mob boss, (has to get a cut of the others food) and looks like Garfield

His name is Finley and his usual nicknames are Fins and Bendy Fendy (when he wants attention, he bends in half and raises his front paw and lowers his head). He's ok with whatever we call him, he knows he's very well loved.

His real name is Simon.

He is a rescue and had some issues, like inappropriate peeing. I think positive terms were better to help him adjust.

But I don't think calling our Cali "Lil rose" would make her smell better no matter how many times we say it!

There is the official name with corresponding nicknames and derivatives, plus the generic name or names.
Our cat Sasha was also sishy-Sashy, squish-squash, and also just Princess. Our dog Carson is mostly Buddy, but also B-dog, good boy, and occasionally stink-boy 😏

Call him anything with ‘Roc’ that is most common but ‘Rock and Roll’ is used, so is ‘Rock of Ages’ (we both getting older), ‘Rock my World’ is his name when getting in the car for rides to walks, ‘Rock ‘round the Block’ when we go out to garden. He understands them all.

Cruella, Crella, Crelli, Crue, Peaches, CrellCrell.... barky von schnauser

haha many names.

not even Pepe Le Pew!

Pal officially because he lived on the Palapa in our house in Mexico. However, he's generally called "Shithead" because of what he did to my husband's head many years ago. He's 28 years old and isn't slowing down a bit.

Parrots live 30 to 50 years. Hopefully your feathered friend will be shitting on heads for another couple of decades!

He's our only pet these days and is a joy to have around!

The Sweetheart name came from my efforts to socialize her with human affection. She was born indoors into a dysfunctional household of multiple related cats, a dog, and several children where the attitude was everyone for themselves. By the time that I got her at age 9 weeks, she had been attacked once by her older half brother. She was the runt of a 3 kitten litter and had to fight for a spot to nurse. I saw her human try to "toughen her up" by flipping her on her back and rolling her around while the tiny little kitten struggled to get free.

So Ember was hyper defensive when I got her home. After she stopped hissing every time I touched her, she trusted me enough to climb up the bedspread and sleep near me. I talked softly to her while petting her head, saying stuff like, "You're such a sweetheart. Just a scared little kitty who is really just a sweetheart inside."

So she associated the word "sweetheart" with affection and has heard it so often that she responds to it like she does to her name.

He was a spoiled rotten cat.

I also nicknamed him Kittenus (he was 20 pounds when he passed), Mr. Kittenus, Catus, Kittenus Rottenus, etc.

We call him Big Boy a lot. I also call him Doof, or the full Doofus. He just a big, lumbering lapdog so he reminds me of a doofus, even though he's smart & listens well.
He answers to both just as readily as his real name.
