売れ残りのハムスターって英語でなんて言うの？

「売れ残りのハムスター」をa hamster that hasn't found a home yetと表現するのはとても素敵だと思います。商品であれば普通は「売れ残り」をleftoversやunsold itemsと呼びますが、動物にそのような言葉を使うのはさすがにちょっと冷たいです。なので、「売れ残りのハムスター」はan unsold hamsterよりa hamster that hasn't found a home yet（まだお家を見つかっていないハムスター）の方がふさわしい表現です。

例文
There is a hamster at the pet shop near my house that hasn't found a home yet. I'm thinking about bringing him home.
家の近くのペットショップに売れ残りのハムスターがいて、お迎えしようか悩んでいます。

"売れ残りのハムスター"
- an unsold hamster
- a leftover hamster
