To give you an idea of current sizes, the best production methods make it on silicon wafers.

One imperfection would compromise the physical integrity.
Even at wafer sizes the sheets are not perfect.

Remember we are talking about a single atom thickness. You can't compare it to anything in the tangible world. Even a highly polished mirror that appears and feels smooth has more than a few atoms of bumpiness.
But if they know for sure it's 200 times stronger than steel, then they can surmise if it would be possible, no?

If it is correct (that it could support a cat) are you saying noone knows the answer yet to the questions I asked?
