I have 534 mods.
I can tell you some of them-
I remember I have A LOT of CC from The Sims Resource, which is a great site that lists a TON of mods from any sims game.
To be specific, realistic hairs, makeup, beards, even skin. And some eyebags.
I have the Troublemaker (I think that's what it's called) Default Replacement Eyes for the pets.
I have a creation by RemusSirion for my Sims' eyes.
I have a lot of random pet cc from far and wide- Tumblr, Instagram, TSR.
For instance, the Fin Tails and Ears, and the 7 Tails for Dogs and 3 Tails for Cats.
I also have pet cc from TheKalinotr0n and a website called Nexus (I think).
