I like to encourage wildlife so blocking any gaps in the fence isn't
worth it, plus I doubt it would work because cats always find a way in,
it might work for the big lug of a ginger tom I doubt he's that agile.
In raised beds and newly dug ground I often poke sticks in at regular
interviews this does seem to help and the citrus peels I scattered
around do seem to have worked too, except the regular feline visitors
have used another area of the garden to muck all over instead yay I'll
just have to eat more oranges and grapefruit.
