I actually had this happen this weekend while away from home. I apologized, explained I was currently out of town and couldn’t… But immediately snapped a couple of quick photos when I was doing a quick check on everything when I got home last night.
Easy peasy.
Iirc… You aren’t supposed to delete ANY animals except if there was a mistake and you double listed. You’re supposed to archive them. But people will just delete anyway. Though some of the older listings do seem to be lost to the 404 monster of time.
Edit:
Some insight to the 404 may also be mentioned here. I guess it can also maybe pop up if the listing is made private.
