  • Happy International Black Cat Day! I live with 3 Black cats. They're smart & have a lot of character. And shiny, velvety fur. They're more expressive than some humans. #blackcats #BlackCatDay #CatsofBluesky #CatSky #InternationalBlackCatDay

every network with a public tag surface

Follow #blackcatday straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.

Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/blackcatday
