No worries - you can also try a general search for the tetherspout keyword in lemmynsfw for prior posts/comments (there aren’t too many results)

The cage is totally separate from the thing called a tetherspout (heres the website from the inventor of it - the chronicles tab has lots of info/pics of it’s potential uses) which has been a great toy for me - I discovered it about a year or so ago via someone else, see https://lemmynsfw.com/post/5809123

The inventor of TS no longer has inventory to sell. The cheaper version (under $20) can be found on Amazon TS, and the titanium ones approx $100 is at bawrpro TS
