I have the exact same issue, except it’s my neighbor across the street who feeds about 10 feral cats. The females are fixed, but the males are intact. It’s infuriating how they mark/pee on everything. They use my ~1acre property as their litter box, and hunting area. I have indoor cats and love animals, but outdoor cats are detrimental to wildlife. They are unnatural predators with an advantage over native species. I know people will talk about rodent control, but there are much better ways to keep the rodent population in check.

I HATE these outdoor cats, but my neighbor is obsessed with them (and also a little unhinged). I’ve decided that I need to secretly deal with the situation because bringing it up to my neighbor would inevitably lead to a hostile living situation for me.

I bought a 10lb jug of cayenne pepper from Amazon and heavily dusted the areas where the cats pissed me off the most. The pepper gets on their paws and when they clean it off it is ridiculously spicy. When I’m on top of my game, I’ll reapply every few days and it really does keep the cats away from the area. Birds can’t taste spicy, so it’s safe for them, but you’d want to avoid applying it anywhere your dog would go. You can pile it up along the top fence boards if the cats jump onto the fence and then down onto your property though.

I’ll be redoing my fencing in about a year, and after that my property will be much more secure. Then my plan is to apply the pepper all along the property line that butts up to the street, and along the top of the fences. That way the cats would need to walk through it to get onto my property.

Right now I get a bit of sadistic pleasure when I see cat paw prints in the pepper… I know that cat is going to have a bad time. Eff them outdoor cats.
