My neighbor has several cats that are not licensed, spayed/neutered, nor controlled. These cats are ALWAYS in my yard. My yard seems to be their toilet! That being said, you would not believe the flies that are on the outside and inside of my house, not to mention the stench! I bought one of those easy set pools...the enjoyment of that was short lived. I assume somehow one of her cats ended up in my pool and scurried for its life to get out! That's the only thing I could figure from the many holes in the top inflatable ring. There are woods behind my house which the cats hang out in. And even worse, they're having kittens back there. I can't take this. I've tried the humane products on the market that supposedly keeps the cats away...they don't work. WHAT CAN I HUMANELY DO!?!?!
