Only guess is crawling on cars and leaving little paw-prints, that's the only common thing I can think of. Occasionally known for getting up under the hood or something, which doesn't turn out so well for the cat, either. Though I'm sure individual cats could have their own undesirable quirks.

With dogs, you get the pooping (which is at least half an owner problem), squirrels dig up my yard, gophers same, ants all over the place. Can't say I've ever had an issue with cats, but I trust the creator of the project has a reason, and as a cat lover, I'd laugh my ass off at video of a cat getting hit by surprise sprinklers.

Cats poop too! And flower gardens are some of their favorite spots, because the dirt is so easy to kick back up.

Also my cats like to bite on flowers. Don't know why, they just do.

Cats do need to eat grass. If they didn't have access to grass, they eat any other plant they can find, including flowers. They do that to clean their digestion system from inedible parts(1), as for a home cat, that's mostly their own furballs.

"Cats regurgitate when they eat grass because they lack the necessary enzymes to break down vegetable matter. Does this mean your cat likes to throw up? Well, while it's doubtful that kitty enjoys the act, this up-chucking sensation may eliminate all indigestible matter from the cat's digestive tract, making it feel a whole lot better. This is important because cats eat their prey as is, including both the edible and inedible parts (fur, bones, feathers, etc.)"
