Strange I have cats on both sides of me, and I have never had a problem with them bothering my daylilies. I love for the neighbor cats to come in my garden and patrol for copperheads and other snakes. I think it helps keep the snakes out even if the cats don't actually capture and kill them (sometimes they do). But as far as eating the leaves of the plants, I have yet to see either of these two cats or a few others that occasionally stray into my garden eating any of the leaves. Good to know that it probably would not harm the cats even if they did develop a taste for daylily leaves.
