Could they have gotten out under the mesh?
When cats are ready to pupate they roam.

Hope they're just hiding. I have a mesh hamper that's similar and they attached to the solid part in the corners rather than using the sticks that I put in there for them. But they are good at finding cracks to escape. They may be hanging out under your deck. : )

Thanks sherry and christie,
Hopefully they squeezed out somewhere and will be okay.
