@OP, I don't support your Sugg... (-1)
... Is just like asking/begging for some Free Gift...
I'm completely "in line" with @Celozon's Post/Arguments, and I would have a few more (Arguments)...:
- The last Pound Event 2 or 3 years ago was super-super-nice..., because of the unexpected Effect, at least for me...
- We "already" had last year (2021) x4 "unexpected" Events: 'Ramadan 2021' + 'International Dogs Day 2021' + 'International Cats Day 2021' + 'International Pandas Day 2021'.
All 4 came totally unexpected, ... and were completely nice... Maybe this year again, we "don't know"...!
... Well, I wouldn't be "surprised" if the 'Ramadan' mini-Event would return a bit regularly, fits a bit in the CS "Concept", trying to "please" different Cultures/Religions...
About the Pound itself, yep indeed 700k Pets in it, but those 700k Pets mean a steady Avg of 1200 Pets + 60 Rares + 6 VR's, => x2 or x3 per Day...
=> Do one Pound Event where 100k Pets get donated within 1-2 days, and you can lower all Values I mentioned to 50 Rares + 5 VR's.
@Tess and @Nick were "clever" enough to surprise us with the last Pound Event for CS=10, let them surprise us again for CS=12 or whenever they feel like it, I would say..., no need to "ask", a Gift is a Gift...!

EDIT: => Yep indeed, a similar Event for Items in the 'Lost & Found' could be an Option, "one day", if it comes "as a Surprise"... Can't tell how many Items the 'Lost & Found' currently contains, but I wouldn't be surprised if it's largely over 1M...
"Pragmatic Thinker"...
I don't try to read anymore when Users use ']Size=85[' (or smaller...!) on the Forum or in their Trade Rules..., as this is completely unreadable on Desktop in any Browser...!
