This may not be an option depending on the size of your beds but - chicken
wire.

Stake it down over the top of the soil - and just on top of the soil. Cats
just don't want to step on things that may bother their feet. Most plants
can just grow right through the openings. Some - such as large beets and
other root crops - may be too big to get through the holes but above the
ground crops - leafy veggies, flowers, should be fine.
