Your sans looks okay, your cat probably just loosened the roots that were keeping it upright. For now I would just try to prop it up and see what happens. A chop stick makes a good support, or find something similar. Stick it next to the plant and attach to some of the leaves with a twist tie or piece of string. Should be fine.

Since your cat bites plants, be absolutely sure you don't have a dieffenbachia in the house or on your property. They are the most dangerous of the common house plants for children or pets.

Since Russ brings up the issue of dangerous to kids and cats: avoid Euphorbia

tirucalli ( firestick) too, as the sap is toxic.

Good point Fred, that applies to all euphorb's and quite a few other plants as well. I do think dieffs are the worst of the lot, except for those that are actually poisonous. There's a common landscape shrub down here called Oleander, all parts of it are deadly poisonous.
