# Patrick Li — Founder of PetGuideCalc

> Patrick Li is the independent founder and sole maintainer of PetGuideCalc: software engineer since 2020, cat parent, and explicitly not a veterinarian.

## Role

I am the independent founder and sole maintainer of PetGuideCalc. I write the calculators and guides, check them against named sources, and editorially review every page. There is no editorial team behind my bylines.

## Verified biography

I am the independent founder and sole maintainer of PetGuideCalc. I have worked as a software engineer since 2020, and I build and edit every calculator and guide on this site.

I currently live with two cats. I previously kept a hamster and a turtle.

## Experience

- I have worked as a software engineer since 2020.
- I currently live with two cats.
- I previously kept a hamster and a turtle.
- I am the independent founder and sole maintainer of PetGuideCalc.

## What “editorially reviewed” means here

Review labels on this site describe activities. When a page says “Editorially reviewed”, the review was mine. It is not professional review: until a verified, named professional reviews a page, health-adjacent pages carry a plain “no veterinarian has reviewed this page” disclosure.

## Boundary

- I am not a veterinarian and not an animal-science expert.
- Nothing on PetGuideCalc is veterinary advice; the tools are educational planning aids.
- Professional review of health-adjacent content is limited to verified, named reviewers — my own review is always labeled as editorial.

## Content by Patrick

- [Can guinea pigs eat…? food safety guide](/guinea-pigs/what-can-guinea-pigs-eat/): Every verdict quotes its sources verbatim, including the disagreements.
- [Calculators](/tools/): Each calculator names the published standard or study behind its numbers.

## Material corrections affecting this profile

### 2026-09-14 — Factual correction (Corrected)

Removed biographical claims the evidence base could not support: reptile and aquarium keeping experience, a 2009 web-development start, and backend-employment details. The founder profile now states only verified facts (software engineer since 2020; two cats; a former hamster and turtle), and the private GitHub repository was removed as a contact route.

Affected pages: [/about/](/about/), [/authors/patrick-li/](/authors/patrick-li/)

Rationale: A public trust profile must not manufacture authority. Only claims with confirmable evidence stay; the previous copy overstated direct animal-keeping experience.
