My Giant Succulent/Cactus Plant...That Will Not Stop Growing

Hello everyone. I am new to this website/forum and to be honest, I joined because I am absolutely clueless as to what kind of plant I have. Any help would be appreciated.

Does anyone have any clue what this plant is? How big does it get? Can I cut it back? What can I do about this?

I got this plant from the Farmer's Market in July when it was about 4 inches tall. I don't think that this is a cactus, but that is what I was told when I bought it (along with 2 other cactus in the same planter). It might be a succulent of some sort, but I have no idea. Some characteristics: the leaves are thick and glossy to the touch. The stem is very, very thick at the bottom...it resembles a small, green tree trunk. The leaves sometimes get these little pods on them that look like new leaves but they're actually seeds and when they drop, they seemingly sprout overnight. This looks a little like that cactus like thing posted below on this board, but mine isn't so dense and it definitely does not smell or have any beautiful flowers.

The thing is too big for its own good. It is tilting over and there is a big ugly Clorox box around it with a ruler attached to try and keep it growing straight (which as you can see, does not work too well). This leads me to my next question: is this plant poisonous to cats (or animals in general)? Another part of the reason why we have the box around it is so that the cat will stay away.

My girlfriend constantly threatens to kill it if I don't figure out what to do with it sometime soon, so thanks for the help!

PS

Sorry for using a camera phone and not my digital camera...hopefully it is still possible to tell what kind of plant this is.

Hello nofx8881, welcome. Very Happy

Kalanchoe diagremontiana ("Mother of Thousands")
which you will also find under the older name Bryophyllum diagremontiana.
Click here for a pic of one like yours (only much smaller Smile

).

Yours looks a bit lanky, which is probably due to getting less sun than it would like.
They grow more lush and less tall if they get lots of sun.
They like to be kept moist during the summer
but give it less water in winter.

Oh, and did I mention they like plenty of good, bright light?
Really - these guys can thrive outside in full sun in the summer.

K. daigremontiana contains daigremontianin,
which can affect cardiac function if ingested,
so yes I'd call it toxic, as are a number of Kalanchoe species.
