My Mother-in-Law Got a Kitten at 77 — A Recipe for Chaos?

My 77-year-old mother-in-law got a kitten, and I’m frustrated. She lives alone, her health is shaky, and kittens are a ton of work—feeding, playtime, vet visits. When her health worsens, I know I’ll be stuck handling it. I suggested a fish, but she insists the kitten is her “companion” to “keep her active.” Active? She can’t chase it! It feels like a disaster, but no one else cares. My husband says, “Let her enjoy it,” but I foresee chaos. Am I overreacting, or is this a mistake? Should I push her to reconsider or just prepare for the fallout?
