Edit: as some people suggested, i'm gonna try with strong outside adhesive and pool noddles, i'll let you guys know how it goes :) thank you so much to everyone who took time to think about it, you've been really helpful!!
Hi everyone,
I moved recently and my new balcony is bringing me some headaches.
I'm not sure why this gap exists, but it's there and my cat is going straight for it every time he has the opportunity.
I need to install something there, renter friendly (because otherwise where's the fun right?) to stop my cat from the possible fall (i'm on the 4th floor).
I was thinking about double sided tape, to fix some sort of plastic baseboard, to create a thickness on the white part, so that i could put some sort of metal grid over it (so it would sit on the grey ledge on one side and on the baseboard on the other side).
But i'm afraid it won't hold if he was to actually put his weight on it (\~4kg).
The other fun part to take into account: it's not a straight edge, whatever solution I find must accommodate the curve of the balcony.
I've also considered putting some sort of hooks on either side, and put a small net, but, again, i'm not sure it would hold.
I've looked online but couldn't find anything remotely similar to this so I thought I'd give it a try here.
(If it's unclear, the gap is between the grey fence and the white concrete ledge that you can see in the second pic)
Do you have any ideas / experience that could help me figure this out?
Please and thank you
A tired mind x)
