The only non-herb plant I have is an aloe vera that is growing in a hanging pot at the kitchen window. That's because of cat - plant issues. But, I haven't had that problem with shreddy and herbs. I did smell basil on his breath the first day the plants came indoors, but never since. And yesterday he horked a little bit of chive, but that was the first time. And these plants are in pots on the floor. Herbs may be too pungent for the kitties.
