Cattleya crawling out of its pot

[Roberta]

I would cut it right next to the last brown pseudobulb. The green one right in front of it might have a decent root or two attached, so even though that pseudobulb is also pretty pathetic, I'd leave it. That will reduce the size to where it can easily fit into the original pot (with fresh medium, of course)

To help that "pre-potting" soak be even more effective, you could put a small amount of sugar (about 1/4 to 1/2 teaspoon per liter) in that water. I have seen the sugar trick prescribed as an extra "boost" for rescuing plants that became severely dehydrated in shipping (like 2 weeks in transit from China), would be appropriate here too. Can't hurt and may help.
