What a bittersweet story. It's as if your Daisy telepathed to her that these humans really needed an assist. (I do believe cats communicate non verbally with one another, just not sure how it is done). And Little Tortie got inside for some loving and cuddles, mending her broken heart while providing a bit of a bridge for yours.

RIP Little Tortie, have a great romp in the meadows at Rainbow Bridge
