Nothing you do to the fence will keep out other cats who
jump in from outside beyond the control of the fence
and cat keeper...

Sounds like this cat lady needs to build a kennel
in her yard where the cats can go inside and outside
of the house but when outside are completely enclosed
in a caged off area... That is the ONLY possible
solution that will prevent escape of her cats and block
ingress of strange cats...

The great Evan has spoken.
