Hi Diana. As always, most of these plants toxicities are unknown. However, from a quick read, it looks like a grass so toxicity would be very unlikely.

Hi Katy. The items marked with an asterisk (*) have no data but widespread usage suggests that they are safe.

Hi Aisha. I discussed this in the article.

Hello! So is Lilly Pilly toxic?

Hi Deanna. That’s why I wrote this article! There’s so much information out there, and given the lack of hard facts in many cases it’s up to you to examine their credentials carefully.

Both my cats do have pica due to being kept in a guinea pig hutch when they were kittens… they didn’t get to do all the normal kitten things like chewing to work out what is good to eat and what’s not. Plus boredom and chewing on what ever was in the guinea pig hutch was prob one of the few things they had to keep themselves occupied. So it’s prob not a genetic cause but a psychological behavior learnt due to mistreatment as kittens (not by me)… one of the 2 is definitely worse than the other (electrocuted herself recently by chewing through my wifi cable) but they both target plants as one of the main things. A neighbor dropped off a passion fruit vine for me to give to my dad. I put it down for a about a minute and when I came back both cats were chewing on the leaves. Then I had to google if passionfruit vine is poisonous to cats… half the info said it’s not and half said it breaks down to cyanide in the body… maybe depending on which variety, but I had no idea, so I spent a stressful night watching to make sure they were ok (they were). So this is why I want to be careful about what I plant. Thanks for the extra advice.

Hi Kelly. True pica is very rare (I have not seen one in my career), so the odds of two cats being affected in one house are minuscule. They sound quite normal to me – most cats will make a mess of any foliage inside the house, probably because there isn’t much choice. Once they have access to larger amounts of greenery they usually settle down and just nibble on it. However, if you’re worried, avoid plants with long strappy leaves or grasses with runners like buffalo, couch and kikuyu. If they truly have pica, there may be no such thing as a safe plant though.
