There is an entire clade of small creatures filling rodent-like niches that have evolved the ability to store an electric charge in capacitor-like organs below their eyes. They can discharge these organs into any would-be predator attempting to eat them. These critters are called `sdFrdFg`, which (very loosely) translates to “zap rats”. Zap rats have even developed aposematic coloration, bearing mostly bright yellow fur with white, black, red, or blue accents being present in varying degrees depending on species. Unfortunately for the zap rats, the yinrih LOVE the mild shock they get from eating them. It's like sticking a 9-volt battery on your tongue. They're either eaten live or, if you don't want to risk them going off in your gut instead of your mouth, you can quickly kill them by holding the animal between your inner and outer thumb and puncturing their dorsal nerve cord with your writing claw.

There are frequent population booms, necessitating regular cullings, with hunting being the preferred method. The zap rats' bright yellow fur makes them trivial to spot.
