Modder KangieDanie has uploaded a splitscreen multipawer – sorry, multiplayer – mod for PC that lets you play through the campaign in local co-op.
User JADabandon asked KangieDanie whether online play was in the scope of this mod, and they responded by confirming that their mod will only focus on getting local co-op to work.
Thanks to the recent release of Stray, the internet is in no shortage of cat content.
KangieDanie notes that the mod is in very early development so if you decide to give it a try, you’re inevitably going to run into some bugs.
