Oh I am so sorry to hear of your loss...
When I lived in an apartment it had a white fenced in patio. Bailey would run out between the posts and I would have to jump the railing or run out the front door to catch her. I went to Home Depo and bought closet shelving (Get the deepest onw) Have it cut to size you need, and attach it with plastic zip ties. It is wire covered in vinyl and it worked great for me, and it didn't damage the apartments building and matched the white railings. Hope that is helpful to someone.
Again so sorry for your loss...
