It was 3 a.m. when the shelter’s night drop-off buzzed. Inside the carrier: a trembling 1-year-old stray mom and three cold, mewling newborns one already limp. The note read: “Why Would a Mother Cat Abandon Her Kittens? She left two in the alley please save them!” The mom, now named Bella, had relocated the healthy ones but ignored the runt.
I warmed the kittens under a heat lamp, tube-fed the weak one, and reunited them with Bella in a quiet nest. Spoiler: Stress + inexperience Bella was a first-time teen mom. After 48 hrs of hand-rearing support, pheromone calming, and gradual bonding, Bella accepted all four. The runts? Thriving fosters now.
