I just let the dog have at 'em. I can always tell if there is something under the cover as he just sits at the back of the boat and stares. I have heard cats make some noise that I never they would when the dog gets under the cover.

I have also found that a live trap works well. Although the neighbors are not that happy when you take their cat back to them in a cage.

fox urine?

Try citrus or Orange oil. Cats hate the smell of citrus. And your boat will smell better! (From Howard Garrett, The Dirt Doctor)

Getcha some fox urine. Worked for chasing critters out of the attic. Just secure the jar so it doesn't spill.

catch them around it and throw a couple firecrackers at them... never knew a cat could jump 10' straight up , did ya???? LOL!!

Cats hate the smell of Lavender as well. Most of the Essential oils will work.

Tie your dog up in the boat!

Lemon extract. Hold it up to cats nose and watch the reaction

iv'e sprayed ammonia on trash bags before when i was having trouble with cats and it worked well

my simple solution was my dog when i was having problems with cats walking on my car... my buddy uses his bow

I have the same problem - liquid childrens Tylenol would work but it has almost the same side effects as antifreeze. I had a problem with skunks and the fox urine got rid of them but the cats still come around. I might try the ammonia or citrus stuff.

should i just spray it into the carpet on the rear of the boat where they come in?

TNT..... and I dont mean the slab.

Cayenne pepper works wonders and it cleans out real easy with just water. You'll never have another housecat or coon come back...once they lick their paws (especially cats) they'll never ever come back.

I covered my truck with it one night and have never had my sister's cats back on it again...they run when they see my truck pull up in the driveway.

lol
