It's not going to matter what plant you get, as your cats are going to make a beeline for it and give it a good tasting just as soon as it arrives inside your home. I have one cat and an apartment full of house plants. My cat ignores all but two of them... my spider plant and my jade fingers plant. The jade fingers are delicate and fall off the trunk if you so much as look at them cross-eyed, so the cat loves to bat at them just to see them fall to the floor. The spider plant gets a good chewing every few days or so. Sometimes it makes her sick, sometimes not, but no matter where I put it, she will find a way to get to it, and will proceed to eat it just as fast as she can. I stopped fighting it long ago and that seems to keep her plant nibbling under control more than anything else. One thing though... I tried giving her a plant of her very own, a live catnip. I even placed it on the floor where she had immediate access to it. She ignored it completely and continued to chew my spider plant. She only likes catnip when it's dried, so I gave up on that idea too. These days when I get a new plant, I just show it to her first, let her sniff it all over and then when she's lost interest, I place it in my window with the others. That method seems to satisfy her curiosity pretty fast, but she still thinks of the spider plant and jade fingers as 'hers'.
