Airport's official accessibility page (confirmed via direct fetch, still current 9 months post-opening) describes the indoor (airside) relief area as for 'working service animals,' not pet cats.
PIT opened a brand-new Landside Terminal on November 18, 2025, replacing the 1992 structure. The airport documents an indoor airside relief area on Concourse D (across from Gate D1) and outdoor grassy areas on the Landside side, but the official accessibility page states the indoor area is for 'working service animals,' so non-service cats are restricted to the outdoor pre-security area.
Outdoor, open-air area — high escape risk for a cat outside a carrier. Serves all Landside passengers arriving via the new (Nov 2025) terminal. Field verification recommended — exact perimeter/fencing not documented online for the new terminal.
Serves all airside concourses (A/B/C/D) via the post-security people mover. The airport's own accessibility page states verbatim that 'working service animals' may use the post-security relief area — non-service cats appear to be excluded. Surface inferred from typical indoor SARA construction; not confirmed by airport's page.

Serves all Landside passengers arriving via the new (Nov 2025) terminal. Field verification recommended — exact perimeter/fencing not documented online for the new terminal.
