What Furscopes is
Furscopes is an independent project that turns a pet’s birthday into a keepsake: a free Cosmic Profile after a short quiz, and an optional full reading for a one-time $9.99 — no subscription, no recurring charge, and a refund if you write to us within fourteen days.
It is entertainment. We use astrology as a lens for writing warmly and specifically about an animal. Nothing here predicts the future, and nothing here is veterinary, medical, nutritional or behavioural advice. For your pet’s health, ask a veterinarian.
The sun sign is the one thing we compute ourselves
The date ranges printed in horoscope columns are a convention, not an observation. The sun crosses into each sign at a specific moment that drifts about six hours a year and snaps back after every leap year. For eight of the twelve signs, the printed start date is the minority outcome; Aries is printed as March 21 and began on March 21 exactly zero times between 2010 and 2027.
So we computed all 216 crossings for those eighteen birth years with the Swiss Ephemeris (pyswisseph, Moshier) and cross-checked every one against NASA JPL DE421 via skyfield. The two agree within two seconds on all 216. We publish the whole table free, under CC BY 4.0, at our open zodiac data page — you do not need us to use it, and you can check our arithmetic against anyone else’s.
A sign boundary is a moment, not a day. If your pet was born on a boundary day, the pet zodiac calculator shows both candidate signs and says which one the year’s crossing actually favours, instead of quietly picking one.
The rest of the chart comes from an ephemeris service
The paid reading includes an appendix of the astronomy behind it. Those values are computed from the birth date by a third-party astronomical API, and not everything in the appendix is astronomy — so we label the sources separately rather than folding them all under one impressive word.
| What | Where it comes from | Note |
|---|---|---|
| Sun sign | Our own table | Swiss Ephemeris, cross-checked against NASA JPL DE421. Published free at /zodiac-dates. |
| Planet placements, degrees, retrogrades | Third-party astronomical API | Computed from the birth date. Printed in the appendix exactly as received. |
| Dignities, asteroids, Sabian degrees | Third-party astronomical API | Traditional astrological readings of those same positions. |
| Eclipses and retrograde stations ahead | Third-party astronomical API | Only the ones that touch a placement we actually have, and only future dates. |
| Lucky numbers and colours | Numerology, not astronomy | Derived from the digits of the birthday. We label it separately rather than calling it astronomy. |
| Chinese zodiac year | Lunar calendar, not astronomy | A different tradition with a different calendar. Also labelled separately. |
The free reading does not call the ephemeris service at all — it uses only our own sun-sign table, so the free path stays fast and the paid path gets the full calculation.
What we throw away rather than invent
This is the part most pet astrology sites skip, and it is the part that decides whether any of the rest is worth reading.
Houses, the rising sign, the midheaven
All three are derived from the exact minute and the exact place of birth. A puppy from a shelter has neither. The calculation refuses to run without some time and place, so we hand it a neutral placeholder — noon, at the Greenwich meridian — and then discard every output that depends on that placeholder: the houses, the ascendant and descendant, the midheaven and IC, and the “house activation” an eclipse service reports. Those numbers would be fiction with a decimal point on them. A rising sign for a pet is a guess dressed as a measurement.
A moon that sits near a boundary
The moon moves about thirteen degrees a day, so on some birthdays the true moon sign genuinely depends on the hour nobody recorded. When our placeholder noon lands the moon near a sign boundary, the reading names both candidates and says plainly that the birth time would settle it. It never picks one silently to sound more confident.
The short version
We calculate what a birthday can support, we publish the table we calculate it from, and we delete the rest. A reading that told you your rescue cat is a Scorpio rising would be telling you something nobody knows.
What the model writes, and what it never touches
The prose in a reading is written by a language model, grounded in the computed values above, under standing rules: no predictions, no health or behaviour claims, and no astrological specifics that the data does not support. Where a traditional source is stark — some Sabian degree images are — the rule is to translate the underlying theme into warmth, never to describe harm to an animal.
The appendix is different. Placements, degrees, retrograde and combust flags, eclipse and station dates are copied straight from the calculation into the page without passing through the model. That is deliberate: it makes fabrication structurally impossible in the one place where a number is a promise. If you want to see exactly what a buyer receives, the whole thing is public at a finished sample reading — nothing blurred, nothing held back.
What we will not claim
We will not tell you that your dog will be ill, or lucky, or that a retrograde explains a behaviour problem. We will not tell you an animal’s breed, health or temperament from a birthday. Astrology is not a science and we do not dress it as one; what is accurate here is the astronomy, and what we do with it afterwards is a portrait. The dog and cat sign guides keep the same line.
Who makes this
Furscopes is an independent project, not a content farm and not a marketplace of astrologers. One person builds it, writes the rules the model works under, and answers the mail. That address is support@furscopes.com — a real inbox, and the fastest way to tell us a number on this site is wrong.
Payment is handled by a third-party provider acting as Merchant of Record, named on your receipt. What we store and for how long is set out in the privacy policy; the terms of sale are in the terms and the refund policy.
Questions we get
Do you need my pet's exact birth time?
No — and we could not use it if you had it. Everything we publish is computed from the birth date alone. That is a real limit, not a shortcut, and it is why we leave out the parts of a chart that depend on the hour.
Why does my pet have no rising sign?
The rising sign, the midheaven and the twelve houses are all derived from the exact minute and the exact place of birth. Almost no pet has a recorded birth time, and a rescue may not have a recorded birthday at all. We would have to invent those numbers to print them, so we discard them instead. Sites that show a pet's rising sign are showing you a guess.
Where do the planet positions in the paid reading come from?
From a third-party astronomical API, computed from your pet's birth date. They appear in the appendix of the reading as a plain table — body, sign, degree, retrograde or combust — so you can check them against any ephemeris you like.
Is the reading written by AI?
The prose is, and we would rather say so than be caught. A language model writes the four parts from the computed values, under rules that forbid prediction and forbid health or behaviour advice. The numbers in the appendix never pass through the model: they are copied straight from the calculation, so they cannot be invented. You can read a whole finished example at /sample before paying anything.
Is any of this scientific?
No. Astrology is not a science and we do not present it as one. What is accurate here is the astronomy — the sun really did cross into Aries at that minute, the moon really was that phase. What we do with it afterwards is a portrait written for delight.
