Thanks for making this thread (and I hope its okay to bump this?) as trying to find cat safe indoor and outdoor plants that won't harm our upcoming new kitten has been quite difficult but I love having oxygenating plants in my house and a bit of colour in my garden. I bought some sage seeds for my herb patch but a friend recently told me sage is actually toxic to cats? I was not aware of this (it is also absent from your list) so I'm not sure if this is simply a myth but there is very little information on the packaging. Also does anyone know if lupins are okay? As I have quite a country cottage type garden with lots of catnip, lavender, lemongrass, thyme and a few apple trees. As far as I'm aware everything on that list bar the lupins which I still have a question mark over are cat safe. I'm also unsure whether or not to keep my indoor chilli plant and christmas catcus?
