Fur babies. They steal your heart before you even realize what's happened.
Eighteen years ago, my little brother worked at the Yakima Humane Society. He called me to ask if I could foster a kitten they'd found in an alley, skinny, hungry and flea ridden. She didn't meet the required weight to be spayed and the only other option was to euthanize her.
I agreed, with every intention to only foster her and return her to the Humane Society once she packed on enough pounds.
