On a weekend away years ago, a co-worker agreed to care for my cats. He couldn't find the house key left for him, and didn't attempt to contact me. “They're just cats.” he said, shrugging.
Cats who don't eat for 48 hours may develop fatal liver conditions. Thankfully, my cats were ok, but gobbled food and water like the starving pets they were.
Years later when starting my own business, this memory, along with another where my son's friend took good care of my pets, but neglected to notice broken lawn sprinklers during a week-long trip of 95 degree days in August, reminded me of the need for someone dependable to do these jobs.
I also knew many seniors who could no longer drive, (or just didn't want to) and whose physical limitations prevented them from shopping or doing other errands. Performing these tasks is a need I can and do fulfill.
