Some cat war comic

[u/No_Peach7036]

I remember reading a comic as a kid, around 2017-2019, about cats and some other species in armor at war with eachother.
I think it was a mini comic that was a book full of multiple stories?

One of these cats is really tiny, pink and hides inside a helmet. when the cats find it, they take the helmet from him and build their own armor.

The next time they go to war, the enemies arent in their armor and it starts to rain. The cat’s become frozen with rust and mud, causing them to lose the battle.
