I agree with Lycopus, it's not a pitcher plant, it is Jack-in-the Pulpit, (toxic).

Spathiphyllum (Peace Lily), Croton, Syngonium, more Spathiphyllum, Palm, Polka Dot Plant (Hypoestes). 'Baby Safe Houseplants' says Spathyphyllum and syngonium contains 'calcium oxalate raphides. If eaten by a child, these plants can cause pain, swelling, and intense irritation of the mouth, lips and throat." They can also cause digestive problems and the worst case the swelling might cause obstruction to the airways. According to the book, the others aren't likely to cause problems. If the cat seems uncomfortable a call to your vet is probably in order. FWIW, my vet had me call the (human) Poison Control Center when I found my cat eating Poinsettia; they were very helpful and didn't seem to mind answering questions about pets. ASPCA also has a poison hot line for animals, but I think you have to pay for it. Good luck. WW

Will- Your Abies balsamea 'Piccolo' looks okay to me. Abies fraseri 'Fastigiata Compacta' - this is likely the result of propagation of a side branch (tertiary, horizontal, rather than secondary vertical) and would be considered a cultivariant. It should develop a leader within a few years. Unknown fir: look up Abies forrestii Abies koreana 'Glauca' - could be 'Glauca' - do you have a spring/early summer photo, would be easier to make a guess. Abies koreana 'Green Compact' is likely the same as 'Compact Dwarf' Cheers- Brent

It's tansy or golden buttons, Tanacetum vulgare.
