Uncaged pets (including cats) are prohibited in the terminal — only service animals may be out of a carrier outside the designated relief areas. The post-security relief area near Gates 12–13 is reported as outdoor fake grass on concrete, not an enclosed indoor room, so a cat cannot be safely let out of its carrier there.
SNA has three relief areas: two outdoor pre-security (Terminal A and Terminal C arrival levels) and one post-security near Gates 12–13. The post-security area is best-described by third-party sources as fake grass on concrete — i.e., outdoor or semi-enclosed, not a sealed indoor room. Uncaged animals other than service animals are prohibited in the terminal.
