Violence is infrequent but moderately bloody at times.
A stabbing of a character is displayed (partially offscreen), but is revealed to be part of a show in Search Party's universe.
Animal cruelty is featured in season 3 and in season 5. While the killings aren't actually shown, the bloody aftermath of one of these cruel incidents is seen. There are also some loud, disturbing sound effects during the killings (skulls being bludgeoned, animals crying in pain and fear).
Lab rats are killed during an experiment in season 5. The rats are not shown or heard dying, but the viewer does see rat carcasses afterward.
