Not sure if this was mentioned yet, but CharityCodes has created a
replacement for the outdated Playable Pets mod. This is not an update but more a mod of note. https://modthesims.info/d/678890/selectable-pets-always.html
From the mod description...
There is an old, out-dated mod called Playable Pets that causes lots of errors. This mod is NOT an update to that mod. It is a complete rewrite as I did not look at the orignal mod's source code. I also did not add any of the translations for the pet commands. Another way to achieve the same results is to install a mod that enables cheat commands that have been disabled and use pets.toggle_selectable_pets but this gets reset to off and needs to be entered every time you load the game or load into a new lot. This mod enables the functionality of the cheat command pets.toggle_selectable_pets to on for every game load and zone.
