Our neighbor's cat keeps pooping in our mulch and around our yard. Is there a safe and effective way to stop neighborhood pets from doing so? Has anyone used a method that works well?
The usual advice (eg. on UK's "Gardener's Question Time") is to get some lion or tiger manure or urine, and to put that along your boundary line. At one time you had to wait until the circus was in town, but I think I heard somewhere that it was possible to buy big cat urine extract for this purpose. (It isn't a problem we have - we have a dog instead.)
I just did a quick Google and came up with a few including this which is pellet form so probably not as smelly.
There are so many potential puns here, let's just assume I said them all...
I've had good success with coffee grounds. I ask Starbucks for a bag of it every now and then and spread it evenly over the entire garden area.
The cat seemed to appear much less frequently after I started using it.
Cats tend to steer clear of very strong-smelling plants like mint and citrus, so you can plant these as deterrents in the areas they like to frequent.
Below are a few other options you may wish to look into:
Liquid ammonia poured into a few small dishes (I use screw-top jam lids) and placed in areas you wish to discourage cats from frequenting is effective. I only use this method in areas away from the house due to the smell...
The herb Rue is said to effective.
As too is the "Scaredy cat plant" (now as the "Pee-off plant" in Europe).
Sprinkle Cayenne pepper onto areas you wish to discourage cats from frequenting is also said to work well. Caution/Warning: Going this route will cause the felines some temporary discomfort/pain (burning, irritation of the paws)...
This year I have had such a problem.
I am having partial success with "Ultrasonic Motion-Activated" system as proposed by Mike Perry. By partial I mean that the cats seem to stop pooping in the places where the system is installed, but move to other "corners" of the garden. I have moved the machine 3 times for now, the cats haven't yet returned to the first spot.
In my childhood, my grandparents used to have something like a compost pile, where they also put the fresh manure. And today I suddenly remembered that this was also the "toilet" for our cat. Furthermore, in the spring I spread quite a lot of manure throughout the yard and I am inclined to think it was a bit too fresh. Then, cat poops started appearing throughout the garden, and I even found some on top of the bags that used to hold the manure.
At the time I thought I was dealing with some crazy cat, but today everything has started making sense.
Cats like pooping at one and the same place, and they seem to be specifically attracted to the smell of composting manure. Therefore, they have started frequenting my yard after I added some fresh manure to it.
The ultrasonic thing + removing the poops as soon as spotting them seems to be helping a bit.
Next year I won't be adding manure, especially fresh one, for sure!
The problem is the mulch - cats like anything that's loose and which they can scratch and move around easily, so freshly dug soil, mulch, pea shingle, anything like that is the equivalent of cat litter so far as they're concerned. The best mulch to use to discourage cats is probably coca shell, if that's available - that has a habit of 'bonding' together to create a resilient mat.
Cut branches of holly and berberis do keep them off, but your borders don't look great with these laid all over. Sticks inserted also work, again, doesn't look great. Scaredy cat plant doesn't work, nor does tiger poo, tried it, they loved/ignored it.
The most effective I've found is the system with a PIR connected to a sprinkler - any movement in the garden means the sprinkler comes on. But that only works well if the sprinkler covers the whole area, obviously, and there's another drawback - windy days meaning excessive movement of plants may well trigger the sprinkler. Having a cat of your own helps to keep them out, and I found they don't like the old fashioned mothballs, the very smelly camphor ones - but you have to renew them every few days.
The other last resort (as far as I'm concerned) option is to provide somewhere they can go, like a smallish area of sand, which apparently works well, but obviously will need clearing out regularly.
Holly leaves or other sharp thorny plants are a good deterrent, but obviously only work in areas where you are happy for such plants to exist!
Place clear plastic water bottles in your garden, half fill them with water so it can be seen there is water inside. Cats and dogs mostly will not poop there as it by instinct not to.
Also, you can try putting sticks in your gardens, poking up! If there is no clear place to rest you bottom, then you will find another place where you can.
Go talk to your neighbor. Tell them you've got plants that are poisonous to cats (Do you have daylillies, canna, iris, calla lilly...I just learned these are very toxic to cats) and ask that they keep their cat indoors. Outdoor cats have very short lives.
Otherwise get a covered cat box, fill it with cat litter and put it close to your property line. Clean it every time your neighbors are watching...
I'm kidding. A squirt bottle with plain water works well. They learn quickly and will find another spot. The motion detector water-squirter would make more sense. Good luck...
I buy cheap cinnamon from the dollar store and sprinkle it around. I have to redo it after every rain. It really does work.
Its the behavior of the cats you want to change. Its pretty hard to stop them pooping everywhere without trying to stop them coming in. So if you like have cats in your garden you'll have to put up with it. When we moved house we got loads of cat poo, in a largeish city garden. Using scent markers - tiger urine etc - requires to much and has to be reapplied. Those ultrasonic devices only covered a small area, and were pretty anti social since all the kids could hear them. So every time we see a cat we tend to chase it out, clap at it. Any way to scare it so that it doesn't want to come in pur garden, thus not needing to 'mark' our garden with the scent of it's poo. There's very little poo nowadays.
