I know this isn't exactly about Seasons but I can't find anywhere else that would be appropriate to post my help request. If this is the wrong place, please move or point me in the right direction.

I have a Sim who is stuck trying to raise 20 puppies or kittens. (He got the task before I got the mod to downsize it to 10 so he's stuck at 20.) He's about 18 or 19 puppies and/or kittens through the task or I hope he is. I can't find a way to count them other than in his friends list. All of the puppies and kittens he raised so far are still in his friends list with most of them showing friend and best friend paws, even if the STR and LTR are 0. His Wants window is always full of wants relating to the past puppies and kittens, all of which are now in other Sims homes. Is there any way to clear these critters out so they do not crowd his wants window? I tried everything I could think of with Insimenator but nothing seemed to work after they'd left the lot. I'm not even sure if I can do it in SimPE.
