The synthetic fibre (polypropylene ??) netting used on orchards, grape vines
etc to exclude birds ought to keep out cats too. The mesh is about 2-2.5cm.
This will be cheaper than wire mesh and easier to erect. You should be able
to get it at any Garden
It won't exclude frugivorous beasties with sharp teeth like possums, which
will chew through almost anything to get to a ripe peach. I am guessing the
cats are not eating your fruit but causing other nuisance that they will
probably do elsewhere rather than chew through a net.
