When you adopt a shelter pet, sometimes their name just fits. That’s exactly what happened when one woman brought home a sweet cat named Millie. The name suited her perfectly, and the kitty even responded to it, so there was no reason to change it.
But then a family twist threw her into unexpected drama. Her cousin, who’s expecting a baby, had “Millie” on her list of potential names. Suddenly, the woman found herself accused of being selfish for refusing to rename her cat, all so her cousin could “save” the name for her future daughter.
Is it fair to expect someone to rename their pet for a baby who isn’t even born yet, or is this cousin overstepping?

Naming disputes often spark strong emotions because names carry deep personal meaning. Psychologists note that people see names as tied to identity, legacy, and belonging. That’s why parents can feel fiercely protective of a “dream name,” even if, objectively, names aren’t exclusive property.
But etiquette experts generally agree: once a name is in use, whether for a child, pet, or even a boat, you can’t demand someone else relinquish it. As Lizzie Post, co-president of the Emily Post Institute, explained in a discussion on naming etiquette, “No one owns a name. What matters is how you handle overlaps with kindness and flexibility”.
Research on naming trends shows Millie is a relatively common name, ranking within the U.S. Top 200 in recent years according to the Social Security Administration.
That means plenty of children and plenty of pets already share the name. Experts highlight that sharing names is normal, and it doesn’t diminish the significance of a child’s name.
Veterinarians also caution against frequent name changes for pets. Cats, in particular, learn to respond to their names through repeated association. Changing it can cause confusion and stress, especially for recently adopted shelter animals who are still adjusting to new environments (ASPCA, 2021).
In this case, renaming the cat to appease a relative could actually harm the animal’s sense of security.
From a family dynamics perspective, it’s worth recognizing that pregnancy can heighten sensitivity. Hormonal shifts and the stress of preparing for parenthood often amplify reactions. Still, experts recommend setting respectful boundaries.
Relationship counselor Nedra Glover Tawwab emphasizes that “healthy boundaries are not about being unkind, but about making clear what you are and are not responsible for”.
Let’s dive into the reactions from Reddit:
Commenters leaned into the humor, suggesting the cat be renamed “Carrie” or even “Maleficent” for maximum irony


This group backed the original poster, pointing out that sharing names isn’t unusual




This group emphasized the obvious: Millie was already the cat’s name, and the cousin’s list was just potential names, not sacred property




Some chalked the cousin’s reaction up to “pregnancy brain” and stress


In the battle of Cat Millie vs. Baby Millie, the internet firmly sided with whiskers and paws. Names aren’t patents, and families should focus on celebrating new life, not waging war over a syllable.
Do you think the cousin was overreacting, or should the cat’s owner have made the “kind” choice and picked a new name? And honestly, if you were naming your child, would you really care if a cat shared it? Drop your thoughts below!
