What is Cats of the Web?

Cats of the Web is a directory of the internet's most famous, beloved, and influential cats. According to internet culture researchers, cats have driven over 15% of all viral content since 2005. This site documents the cats who shaped internet culture, from early meme icons like Grumpy Cat to modern social media stars with millions of followers.

How are cats selected for the directory?

Cats are selected based on cultural impact, social media following, and contribution to internet culture. Celebrity cats, meme icons, political cats, and social media stars are all represented. The directory covers cats from the United States, UK, Japan, and over 15 other countries.

Can I submit a cat to the directory?

Yes. Use the submit form at catsoftheweb.com/submit/ to nominate a famous cat. Include their name, social media links, and a brief description of why they are notable.

Why make an adoption certificate for your cat?

It marks the day. Many owners celebrate their cat's adoption date, often called a "gotcha day", like a birthday.
It makes a good keepsake. Print it, sign it and frame it next to your cat's first photo at home.
It is a thoughtful gift. Give one to a friend or family member who just adopted, or to a child as their cat's "official" paperwork.

Tips for a certificate that looks great

Use a clear, front-facing photo. It is cropped to a circle, so keep the face in the middle.
Write the date out in words, like 12 March 2026, so it reads well on paper.
Print on thicker paper or card stock and sign with a dark pen.

Frequently asked questions

Is this an official adoption document?

No. It is a keepsake for fun. Your shelter or rescue gives you the real adoption paperwork, and that is what counts for ownership, microchip and vet records.

Is the cat adoption certificate generator free?

Yes. No sign-up, and the only branding is a small credit line at the bottom.

Do you keep my photo or details?

No. The certificate is built when you click download and is not saved. A photo is held in a temporary folder so the PDF can be made, and it is deleted automatically within a few hours.
