Name ideas starting with the same letter

Every time I get a new addition to the rat family I name all of the babies in that set starting with the same letter

Maple and mocha, Sage, saffron and sassafras, pat and pete ect

I would love to hear what you guys would think of when you think of matching letter names

I would love to continue naming each generation of my babies with the same letters but it's getting harder to think of ideas
