Nekojiru-sou, Ginga Tetsudou no Yoru Recommendations
Both are about anthropomorphic cats going on pointless journeys through surreal locations.
Nekojiru-sou also stars a cast of anthropomorphic cats that go on a surreal adventure. Both feature films have darker undertones than at first glance. The art style is also otherworldly and is sure to remind the audience of Ginga Tetsudou no Yoru.
