Catstr is very popular in the hosehold, also the mandalorian 🤣 then quoting the note id the gif is in from the gallery in a note, reply etc. If you already have a gif folder, that goes up easy. Or scraping tenor etc for old movies gifs and so on.

Yo, my favorite new blossom+deno to nostr shit is to scrape tenor #catstr gifs and 🌸 them up now that nostrcheck is in as well, thanks to hzrd149 (nprofile…69jx) Alex (nprofile…al0v) and the heads up of provoost (nprofile…s3js) instagram script.
