SCP Foundation — Secure. Contain. Protozoa.

Item #: SCP-033

Special Containment Procedures

SCP-033 is contained at all times within the bisks.net subdomain lattice, reachable exclusively through the fixed address https://catsofatproto.bisks.net/. As a Euclid-class object, personnel are advised that SCP-033's behavior is only partially predictable under repeat interaction; researchers should log anomalous outputs to the site's own Addendum before treating them as expected behavior.

Description

SCP-033, catalogued internally as "cats of atproto," classified as a utility-class anomaly, is reachable at https://catsofatproto.bisks.net/.

The clearest surviving account of the anomaly's function is its own front-page copy, reproduced below:

████ cat photos off the ███████ firehose. a ███████ or alt ████ saying "cat" is enough to get in; ██████████ else has to pass an actual vision model — MobileNet, running █████ in ████ browser — that looks at the photo and decides for ███████ @norvid-studies asked for a live cats feed.

Terminal access to this file is restricted to personnel with Level 3 clearance or higher. Public link is provided below for verification purposes only.
