OK don't laugh but I had a problem with my neighbors cats pooping on my lawn, daily.
I try like heck to maintain a nice lawn but this went too far, and we called the neighbor / owner who promised to keep the cats in the house. Well that lasted three days and it started again, every single day. I got sick and tired of cleaning it up and it was causing yellow spots all over. And it got in to the lawn mower, lawn bag, etc.
What to do? Get a dog?
I called the police and they suggested calling Animal Control. I got a Hav-a-Heart trap and set a can of tuna in it, and bam! nailed the cat in a day. A.C. came by and took the hissing cat away.
Two days later, more cat poop.
Set the trap again and got another kitty. Called A.C. and they took this cat away.
Solved?
Nope, more poop within a week. Set the trap again, same deal.
Three cats and now the problem is done, I hope.
I saw a new cat yesterday cross the yard.....:uzi:
