This one?

Hi there,
that is an indoor Cyclamen, I did a quick web search, and it seems to be mildly irritating, not life threatening at least.

Did you consider offering some plants that your cat could chew on to draw them from other ones? like spider plant (Chlorophytum) or sprouting wheat

These? I think one's a Zanzibar Aloe

Pretty sure this one is bad for you

This is the last of the one's he could reach, I think.

Agree that the 1st photo is a Cyclamen.

2nd photo is Parlor Palm, with an unhappy Jade (Crassula ovata) hanging downward. And that is absolutely atypical behavior for the Jade, so it may have a root problem?

3rd photo is, I think, a Haworthia rather than an Aloe, but I can't tell you which Haworthia. There's also another succulent in that pot along with the Haworthia. If you don't get IDs for them here, talk to the folks on GW's Cacti & Succulent forum.

The 2nd last is Epipremnum

The last one is a Dieffenbachia (which I know is toxic)

I agree with Haworthia and the other 2 are correctly ID'd

I wonder if the second succulent in the pot with the Haworthia might be a particularly light-starved Sedum multiceps....

You can check toxicity details for plants here.

The succulent with the palm is not a good combo. The succulent (which also looks like Crassula to me too, but hard to tell from it's abnormal appearance) needs much more light, much less water than the palm.

Does someone else care for these plants? The Pothos (Epipremnum) and palm look OK, but the others look like they're having a struggle. If anyone's interested in further details of that type, come on over to house plant section.
