The Critics' Awards for Theatre in Scotland (CATS) are an annual event awarding performances "substantially produced in Scotland, or developed, rehearsed and premiered in Scotland".
The ceremony is itinerant in terms of location, switching between theatre venues in Edinburgh, Glasgow, and elsewhere – for example, in 2007 the ceremony was hosted by Pitlochry Festival Theatre, while in 2019 the event was held at Tramway (arts centre)  in Glasgow.
The Awards Ceremony, which takes place on the second Sunday in June, is open to the general public, not just members of Scotland's theatre industry.
The judges are invited critics who write regularly on theatre across Scotland, for print and/or online publications.
The first CATS, in June 2003 (covering productions between May 2002 to April 2003) announced five awards: Best Production; Best Male Performance; Best Female Performance; Best Design; and Best New Play. Five additional categories were quickly added: Best Director; Best Technical Presentation; Best Production for Children and Young People; Best Ensemble; and Best Music and Sound.
There is also the special "CATS Whiskers", which is awarded to individuals or organisations whom the judges believe have made a significant contribution to theatre in Scotland. The most recent recipient of this award – which is granted only occasionally – was Muriel Romanes in 2016, for "supporting and strengthening women's role in Scottish theatre", most notably as the first artistic director of Stellar Quines Theatre Company.
