I often put herbs in my staggered pots by the door and have found cats there also. I just carefully move them to other less desirable (to me) locations as I use those closest to the door for the kitchen.
I usually let a couple volunteer tomatoes grow for horn worms (phoenix moth), rather than see my crop tomatoes ravaged by those voracious eaters.
We plan to have a monarch bed this year in a co-op with others from a gardening group from the Mid-Atlantic we belong to. Monarchs have been fewer and fewer each year as a result of big business agri-pratices of GMOs and herbicides wiping out their natural host plants.
