The CastP tool just takes the atoms listed as lining the pocket and then shows their molecular surface patches, so what you get may not be a closed surface unless the molecular surface of those atoms really does form an enclosed bubble.
For approaches to get an enclosed surface even when the molecular surface does not form an enclosed bubble, please see the last part of this previous post:
It mentions (A) Surfnet tool in Chimera (B) VVV website to calculate a map filling the space.
Unfortunately showing a cavity blob in Chimera is not as convenient as using HOLE, HOLLOW, CAVER etc. with Pymol since those tools have Pymol plugins. In this previous post, Oliver Clarke provided a script for visualizing HOLE results in Chimera:

Yet another possibility outside of Chimera is MolAxis. At least when I used it a long time ago, it took only minor editing to display in Chimera, as described for this entry in the Image Gallery:
