i've never had a puppy, so i'm not sure about the easier.

but i imagine that puppies are, at the very least, a lot less pointy, and comfine their issues mostly to ground level.

a kitten can get anywhere. (and anywhere includes things like tangled in the blinds, halfway up the window, or overturning laundry baskets on top of herself, or leaping, all four feet akimbo, into a plate of nachos, or jumping into the shower because she thinks you're doing something interesting in there)
