In　this　paper,　we　study　the　Schrödinger　cat　state　transfer　in　a　quantum　optical　version　of　Newton’s　cradle　in　a　non-Markovian　environment.　Based　on　a　non-Markovian　master　equation,　we　show　that　the　cat　state　can　be　transferred　purely　through　the　memory　effect　of　the　non-Markovian　common　environment,　even　without　any　direct　couplings　between　neighbor　cavities.　The　mechanism　of　the　environment-induced　cat　state　transfer　is　analyzed　both　analytically　and　numerically　to　demonstrate　that　the　transfer　is　a　unique　phenomenon　in　a　non-Markovian　regime.　From　this　example,　the　non-Markovian　environment　is　shown　to　be　qualitatively　different　from　the　Markovian　environment,　reflected　by　the　finite　versus　zero　residue　coherence.　Besides,　we　also　show　the　influence　of　environmental　parameters　is　crucial　for　the　transfer.　We　hope　the　cat　state　transfer　studied　in　this　work　may　shed　more　light　on　the　fundamental　difference　between　non-Markovian　and　Markovian　environments.　©　2025　Optica　Publishing　Group　under　the　terms　of　the　Optica　Open　Access　Publishing　Agreement.
