No it will not help. The best thing you can do is shampoo the cats with A1
steak sauce. That will take care of your problems.

The only thing that would scare the coyotes would be the lion itself.
I once lived where we had mountain lions as well as coyotes on the land
behind our house, so I suspect the coyotes were not scared off by lion dung.
We never let our cats outside because coyotes are cat lovers too!

In my area coyotes come out in the day time. They are bold here in LA. You
don't let your cats or small dogs out at all. They will sit in a bush and wait
for someone with a small dog not on a leash to pass by and they'll grab it and
run away with it. The lion dung, fox urine thing might at best help a day. I
suggest keeping them in or making a great enclosed outside area for them. You
could also totally enclose your property with six foot fencing with coyote bars
on the top. That's expensive and you still better make sure kitty can't get
out. Here are more coyote tips. I don't suggest moth balls or amonia as they
are dangerous for kitties.

WHAT YOU CAN DO TO PROTECT YOUR FAMILY, PETS, POULTRY AND LIVESTOCK

Coyotes are capable of scaling fences up to six feet high. They will also dig
under fences. They can be deterred by increasing the height of fencing to a
total of at least eight feet and facing it outward at an 45 degree angle. Bury
the bottom of the fence at least six to twelve inches underground to prevent
the coyote from digging underneath. There is also a rolling bar that can be
placed on the top of an existing fence which will keep them from coming in. A
covered enclosure set up with a pet door will permit your pet to go safely
outdoors.

Chickens, rabbits and other small animals often kept outdoors should be kept in
well protected areas and in sturdy cages at night. Cages made of chicken wire
will not keep desperate coyotes or other predators from entering. Stronger
gauge wiring is a necessity in protecting these small animals.

DO:

*Keep your cat or small dog indoors at night or any other time a coyote is in
the area.
*Accompany your small dog in a well lighted area at night for walks
*Walk your dog on a leash whenever you take it off your property
*Confine poultry and rabbits in covered enclosures with heavy mesh wire.
Coyotes can break through chicken wire.
*Pick backyard fruit as soon as it ripens and keep rotten fruit off the ground.

DON'TS:

*Don't feed wild animals. It's illegal to feed predatory animals in the city of
Los Angeles
*Don't leave pet food outside, particularly at night
*Don't allow pets to roam from home, especially at night
*Don't leave water bowls for pets outdoors
*Don't leave garbage containers open
*Don't leave water in birdbaths or bird seed outdoors for songbirds.

Also, flashing lights, tape recorded human noises, scattered moth balls and
ammonia soaked rags strategically placed may deter coyotes from entering your
property.
