Cats are a generous animal. They allow you to pet and stroke them. On their terms, of course. And they will kindly rub against moving legs as you attempt to walk across the room (usually when carrying something fragile).
They are bighearted enough to keep your seat warm once you vacate it. So long as you no longer want to return to it. And they will help with any paper work that must be done, by laying across the stationary.
But most of all, their abundant nature shows itself first thing in the morning when you leap out of bed and nearly step on the remains of a mouse they gave thoughtfully brought for your breakfast.
Could any creature be more charitable?
