I noticed yesterday that my mini goat and sheep are both elderly. I play on a PC, I have a few mods and a bit of cc. I keep animal aging turned off, but my mini goat and sheep are currently dying of old age (hope there's a few more pets left till the reaper comes for a visit). I didn't realize they had aged up until I noticed they were sleeping quite a lot in the day. Since animal aging was turned off, I had no reason to keep an eye on aging.
I do create a new save file after any updates, and in the previous one (before the most recent fixes (ver: 1.120.117.1030), the animals are still adults. That may be just a coincidence (or that they haven't aged up at this point), but I thought I would mention it anyway.
