Ok, I'm a dog lover. I like cats, but when it comes to protecting my ducks, I'd go with the electric wire. There are bait cups for deer, you attach them to the wire. For a car, fill it with tuna fish, let them get zapped, and likely they'll stay away. If not, put a strand around the top area where they are getting in and more on top the house, so they can't jump up without getting zapped.
If that's too severe, try using mouse traps. The cat doesn't actually get caught in them, but they usually trigger them and the snapping scares them so much, they won't go back. It worked on our cat when it was a kitten. I didn't want him on my counter tops. One time getting scared was all it took! He never jumped up on the counter again.
Last option is a scat mat. They are really for inside, so you should only hook up when it's dry outside. you lay them where you don't want the animal going. It delivers a mild static electricity shock, and they learn to stay away.
Protect your babies. The cat is taking advantage of you. They can learn!
