can’t click sim, can’t click phone on sims 3

@Aprilxoboo  It's possible something about the pets was an issue, but it's pretty difficult to be sure without some extensive testing.  If you happen to use custom content, a pet collar could easily be the issue, but that's just speculation on my part.  Regardless, it's always a good idea to make backup copies of your saves periodically and especially right before you make a major change in-game.  That way, if something goes wrong, you can revert to the backup without losing much progress.

I personally use "save as" to rename my save, which leaves the older one intact under its old name, a few times a sim-week; I get rid of the oldest backups when I'm sure I won't need thm.  That might be overkill for some people, but for me, losing a few hours or a sim-day of gameplay isn't a big deal, and replaying that amount of time is usually quicker than trying to fix whatever's wrong with my current save.

For pet adoptions in general, using MasterController's Adopt Pet command (under Sim > Basic) is much more reliable and less prone to error than calling the adoption service.  The pet pool should be the same either way.
