For a long time, one of my major pet peeves about cats in Sims 3 is their tendency to wait until you're not looking, then pull things out of their inventory and leave them wherever. Who knows how many simoleons I've lost from cats littering the floors with random bugs and minor pets. I've tried to find mods which prevent this, but with limited success. Then one day, while looking through the many things in the GameplayData package file, I came across a solution. As it turns out, there are two separate ITUNs which influence this behavior, and the mods I'd tried in the past only changed one of these.

This mod prevents cats from autonomously dropping prey or presenting it to sims. The behaviors are still available as user-directed actions. I've tested this in my game, and have yet to notice any issues. This modifies the DropSomewhere_ICatPrey and PresentTo_ICatPrey ITUNs, and will conflict with any other mods which change these.
