I made this mod after my Sims' cat refused to eat from the bowl and consequently starved to death and became a zombie. Pets in TS1 for some reason are dumb as hell and don't eat when they are hungry, they will starve to death, but will literally do anything but eat. So this mod just forces pets to automatically eat when their Hunger is low. This interaction cannot be interrupted - the pets will keep trying to perform it until they succeed, even if the path is blocked, so keep this in mind. Since I've been using this mod, none of my pets have died.

Place this mod in the Global folder (MaxisThe SimsGameDataGlobal).
