I have just finished a new article on the various remedies that you can try to deter cats from causing havoc in your yard or garden. I found so much information that I had to leave out some of the more outrageous suggestions, so where better than to record these than in this blog.
One apparently sensible suggestion that you should train your cat to respect your plants is ridiculed by someone else who opined that training a cat not to roam may be like teaching a pig to sing -- basically impossible and a great annoyance to the animal.
A post headed "Grrrrrrrr" continued "I was trying to find the best "cure" for cat problems - 12 gauge, 30.06, paintball, hose, squirt-gun, land mines, rocket launchers, etc. Don't get me wrong, I like cats, but not when they're eating my birds. I'm still working on this problem, but at present, maybe just a touch of TNT in the right place might work, :-)"
A somewhat less drastic approach but nevetheless rather sneaky was this suggestion. Fix some fruit netting two feet above the ground so that when the cat approaches, its paws will pass through the netting but not reach the ground so that it cannot move. Then get your hose and teach it a lesson it will not forget.
For some more conventional and humane cat repellent remedies the article is on my website.
