Peaceful Coexistence

For a few months now the cat and the plants have not had to co-exist and both have been flourishing. Now that they'll be living under the same roof, what can I do to keep them both happy?

Cats have a natural curiosity about plants and a natural inclination for mischief. The sad state of the shamrocks, and the accompanying yak (this a scientific term) are testament to the challenging relationship.

I will probably put the shamrocks out of harm's reach - on a high window sill or perhaps hanging. But I'd also like the cat to enjoy living here so I'm looking for plants that she'll enjoy without destroying or being destroyed.

No poisonous plants like philodendron or poinsettia. For tasty treats I'd like to grow some grass and catnip. Let the excitment begin!
