🏷️ Astrology · 📅 Updated November 8, 2026 · ✍️ By Riley Fox · ⏱ 11 min read
Does your cat demand attention like they're accepting an Oscar? Classic Leo energy. Is your dog stubborn about which route to walk? Sounds like a Taurus.
Zodiac pet names are inspired by your pet's astrological sign, based on their birthday or "Gotcha Day." Think Simba for a Leo, Luna for a Cancer (ruled by the Moon), or Archer for a Sagittarius. Below you'll find names for all 12 signs, grouped by element, plus a bonus: the real star names from each zodiac constellation.
Just for fun: astrology isn't a science, and there's no evidence that a pet's birth date shapes its personality. But sign traits are a playful way to find name inspiration, especially if your pet's personality happens to match.

⭐ Bonus: real star names from each zodiac constellation
For a name that's literally written in the stars, borrow an official star name. These are approved by the International Astronomical Union's Working Group on Star Names, which standardized hundreds of traditional star names in 2016 (Sky & Telescope; WGSN Bulletin):
| Constellation (sign) | Star name |
|---|---|
| Aries | Hamal |
| Taurus | Aldebaran |
| Gemini | Castor & Pollux (perfect for two pets) |
| Leo | Regulus |
| Virgo | Spica |
| Libra | Zubenelgenubi ("Zuben" for short) |
| Scorpius (Scorpio) | Antares |
| Sagittarius | Nunki |
| Capricornus (Capricorn) | Algedi |
| Aquarius | Sadalsuud |
| Pisces | Alrescha |
✨ Tips for a cosmic name
- Don't know the birthday? Use your Gotcha Day (adoption day), or simply pick the sign that matches your pet's personality.
- Shorten star names. The AKC recommends one or two syllables, so Zubenelgenubi becomes "Zuben" and Aldebaran becomes "Aldo."
- Match personality first. A calm Aries named "Spark" is funny; a chaotic one is perfect.

❓ Frequently asked questions
How do I find my pet's zodiac sign?
Match your pet's birthday to the sign dates: for example, July 23 to August 22 is Leo. If you don't know the birthday, many owners use their pet's adoption day instead.
What's a good name for a Leo pet?
Simba, Rex (Latin for "king"), Queenie, and Sunny suit a Leo. For a real star name, try Regulus, the brightest star in the constellation Leo.
Does a pet's zodiac sign affect its personality?
There's no scientific evidence that it does. Zodiac names are best enjoyed as a fun source of inspiration, especially if your pet's personality happens to fit its sign.
What are good zodiac names for two pets?
Castor and Pollux, the twin stars of Gemini, are a perfect pair. Romeo and Bella (Libra) or Sun and Luna also work beautifully.
What sign is ruled by the Moon?
In astrology, Cancer is ruled by the Moon, which makes Luna (Latin for "moon") a natural choice for a Cancer pet.
