Our neighborhood is full of stray cats like over 20 cats and they are ruining our new cars that are cover by clawing into it and putting scrarches on the roofs of car. Pooping all over front yard. Dont know what to do.

That's really odd cause cats, usually don't use there nails when jumping on something stable and burry there poop! But, some people just hate cats!

Call them and ask what steps you can take to have removed safely they were very nice and helpful

Call ACS and ask for help. They have humane traps. Please don't use Visine to make them sick.

Keep calling them, I don't suggest you taking the animals they're full most of the time so keep calling.
