If you adopted a brother and sister from the same litter, you may be interested in choosing names that “go together.” Of course, this is a bit harder to do, since you basically need to put together a “theme” and choose names that relate to that theme. You can also choose names that sound similar or have the same “feel.”

Luckily, we’ve done all the brainstorming for you. Below, you’ll find over 230 names fitting for brothers and sisters.

How to Name Your Brother and Sister Cat

There are many ways to name your brother and sister cat. If you’re here, we’re assuming you’re looking for themed or matching names. There are many ways to go about this. Some people simply choose names that start with the same letter or sound similar. You can take things a step forward by choosing themed names.

For instance, you can name your two cats after authors or characters from movies. In this way, you’re able to choose from a wider variety of names while still keeping them similar.

To start, take a look at our lists below. These provide tons of naming possibilities in a mix-and-match layout. Select the names you like best (or the pairs of names, in this case). Write down all the names you might like for your feline.

Once you have a list of names, try calling your cats by different names to see how they respond. You’ll quickly see which names suit them best based on how “fitting” they feel when you use them. Even though we may like some names, they may simply not fit our cats.

Ultimately, go with the names that resonate with you and feel right for your cats. Trust your instincts and choose names that you genuinely love and feel a connection to.
