Does anyone know of, or have a list for the plants that we should keep away from our cats? Obviously cactus should not be trifled with in low lying areas…but what about english ivy, palms, ferns, pothos etc…etc… Does anyone know?
Here you go. Wow, there’s a lot of them. I only knew about poinsettias and ferns.
Yes, those, and the “Venus Cat-Trap”
If Cat likes to nibble on plants, you can buy cat-friendly substitues for the house-plant gnawing. I’ve had some success with “cat grass” (basically oat grass) and catnip or catmint. I’ve noticed that once kitty has her own stuff to chomp, she tends to ignore the other houseplants.
I question the poinsettia. I thought that had been debunked (although not widely known).
If it’s the incessant meowing, I would try Dieffenbachia spp. . On the other hand if it is the introverted behaviour the air of self importance I would try the non-vegetative method of a cat, a sack, a brick and a river.
Ooops! You want to keep the cat?
Can’t help there.
Seems I misread the OP.
Mars, and definitely Neptune. I’ve heard Pluto is toxic during its springtime.
-Sorry, just popped in from the Bad Astronomer’s site. Need to reset eyes. 
Has anyone here ever had a cat get sick from eating houseplants?
I’ve never avoided poisonous plants, but my cats do: they seem to know which ones to chew on and which ones not to chew on.
I’d be interested to hear if I’ve just been lucky, or if anyone else has found this to be the case.
If ever you needed proof of the difference between cats and dogs, it’s right there in the OP. The cat gets its own capital letter?
Yes. Last year Cookie Monster ate one of the leaves from a daffodil, then barfed all over the kitchen.
Here’s a list of safe plants:

Good luck!
