Not safe if you do not like anthropomorphic violence of cute fluffy animals to other cute fluffy animals. Plus, no English subtitles yet but you can get gist of the scene without subtitles. Also known as Apocalypse Meow in the US, but clearly the original title is preferred.
Story: Packy, Botasky and Rats are special operations experts working in a private military company. Every day they are embroiled in combat somewhere around the world. In the first episode, they intend to come to the assistance of a hostage captured by guerrillas demanding the withdrawal of the US Army, but instead become surrounded by a large number of guerrillas.
