I have started putting DUC tape sticky side up. When the 4Runner and EX are in the garage I open the hood and lay the duc tape on the fenders where the cat jumps up/walks on. As long as the tape is applied the cat has not been a problem. I have left it off and she is right back at it.
The alumimum foil sounds good....
of course winchester sounds good at times also

 

Hey....it only tastes like chicken.....

 

Donc, do you have the keyless entry for your truck? When you catch the cat sitting up there you hit the panic button on the back of your remote! It's great entertainment and it only took me doing that twice to cure my cats of getting on my Runner. They don't even look at it now, they are so scared of it. They think that alarm is going to go off any time they get near it. Afterwards, a little rubbing compound for the scratches and you're all better.

 

put a dish of anti freeze (radiator coolant) on the hood, cats love the sweet taste of it, and it will kill the cat too!!!!

 

Nah, the scope takes away the sport of it all....

 

We use the spray bottle thing when the cat does some thing wrong.

It has conditioned the cat so well, all I have to do is show him the bottle and he runs. It's like a cross to a vampire.

If I set the bottle on the floor, he will not even dare to venture past it.

If it were my cat, all I would have to do is set the spray bottle on the truck and he would come no where near it.

 

I like it
