Looking for a Manga after my reading list is gone

It’s a bl story. Upset it isn’t about one couple there seems to be many stories in the manga. Main couple was a black bunny and fox. They work in a office building. Another couple was about a mouse and a white tiger. They had kids. Uh then there was 2 mouses and a black cat? The cats ear has a nip and the tail is like broken. The poor cat was from a orphaned and wrote to the mouses after he saw them on television once. Thank you!
