Razorwire and an electrified fence. Won't bug the birds, but it'll hurt the hell out of the cats.

Dogsrool (if he were still with us) would have suggested a catloaf:

[QUOTE=Mr. Stafford]gee, its along the top of the fence they use to come into the garden.

the people next door put spikes along the top of theirs for a few feet and it blocks them in their tracks.[/QUOTE]

See I thought you would have already tried the usual method. You just stick a runner on the top of the fence with tacks hammer through it. You can't see the tacks from a distance and the cats stay the hell away from the fence.

Heh, my grandad put them on his fence once to stop the kids next door climbing it.

what about fly paper? would that stick the birds?

It might rip their little legs off.

And I don't think the cats would be bothered too much, youd just end up catching tuffs of fur.

well we cant have that, my garden needs to be a haven for winged beasts and a catpocalypse at the same time.

Just get some sentry guns already.

Or hire some geordies with air rifles.

What ever happened to him? I've been wondering why I hadn't seen him post.
