Cat proof fence?

Electric. See your local agricultural suppliers.

Get yourself a larger cat.

Or a life.

I find 1oz of #9 shot doing about 1000fps most efficacious.

Recently bought 1000 Gamebore 6s from here:

I'm pretty sure that my life would rapidly turn to s*it if I fired a shotgun in my suburban garden.

An experienced working terrier in your garden for a week really is the best bet. Looks like there might be a rental business opportunity.

Why aren't the rollers just stacked on top of each other on the top of the fence?

Why? I have.

(Admittedly on November 5th.)

Its the overhang that does the job. The cat has to jump from the vertical backwards and outwards and then the roller will spin in a direction to drop the cat downwards. If the rollers were stacked above each other the cat could bypass the lower one and then be catapulted outwards on the top roller.

Those fences are primarily designed to keep your own cat in your own garden and not necessarily to keep other cat out.

I can also report that ultrasonic don't work for protecting specific areas.Back in my youth when I could see, I put one of these in the middle of my Mothers garden and the next day two cats were there playing football with it. They could obviously hear it and thought it was something alive. So much for technology.

Lion poo is quite good used to bean able to get it round here but since Chessington became a 'resort' its far too posh to have a stall flogging bags of big cat poo to the public. Brian

Yes they always go to the loo in other gardens. They also have territories as well so a more capable cat may well cause stress to others. Also of course unless you are very very lucky, much of what you attribute to cats is usually urban foxes. they dig under fences and crap and piss everywhere and smell worse than cats. Brian

Or a dog.

I know quite a few people with all three.

Who's going to know anyway?
