Thanks for the suggestion, but they don't take international orders. And
I'm not sure if I could rig that up on the balcony either. I was
thinking of a wire net in front of the balcony, still allowing Laku to
sit on the banister, but keeping him from falling down if he should miss
his footing (or is that pawing??). The net could probably be fastened
with a couple of loop screws at both ends.

And I know Laku wouldn't try to climb it as he doesn't like surfaces
that aren't solid. He doesn't even climb up on the kitty tree which is
the same as Marina has, as the perch in the middle isn't made of a solid
piece of plywood (or whatever) but has a hole in the middle where the
covering fabric makes it into a kind of hammock.

Ah...yes...  They have a free standing version that would be good for
a patio or balcony, and they also have one that has little spikes that
can be stuck in the ground.  My parents got one of the latter for me one
year.  Katie...well...the last time I tried to put her out there, she
tried to shred me.  I *think* that's just because once, a long time ago,
she was out back getting walked on her harness, and got spooked.  Katie
comes zooming back in to the back yard, *no* harness, and launches her
portly little calico self back in to the house.  Since then, I can't
even pick up the harness, or else she'll disappear.  But I digress
drastically...for the sake of the server, actually....

Tripper...*loves* the tunnel.  He'd go hang out and graze all day, flop
half in, half out of the sun, snooze, then get more grass.  I love the
tunnel because I can put it somewhere I'm *not* working, and I don't
have to worry about him getting tangled up, like I do when he's on the
harness.  He purrs, blinks, mrows, grazes...all in all, a pleased
fur kid.  He, of course, waits until he gets back in on the carpet
before he hurks up all that grass.....yech.....

Hazard...also *loves* the tunnel.  Goes out, purring like the little
fiend that he is, kneading the grass and the tunnel netting, grazing,
cheekrubbing the netting, putting his paws up through the top of the
tunnel net and stretching, dashing back and forth, chattering at
the birds and squirrels that decide to be bold.  Yet another happy
fur kid....who also waits until he's back inside to return my grass
to me.....;)

Might be time to invest in more attachments.....;)

And he looks so serious doing it too, or then there's that "demon kitty"
light shining in his eyes and his tail's all "bottlebrushed" out. :D
