OK -- Here's my problem...and hopefully someone can help me out with a solution here. I've got 2 cats of my own (1 male, 1 female, both are fixed). But for some reason, they still attract a ton of stray cats onto my back deck. It irritates me because it's mainly the neighbors cats, who aren't fixed, and they spray.

So, does anyone have ideas for getting rid of pesky strays/neighbors cats? I've found that coating the edges of the deck with pepper spray does the trick for a few days, but hoping there are more economical choices (as OC spray isn't cheap ).
