The idiom no room to swing a cat means a place is very small or crowded, with hardly any space to move around. People use this expression when a room or area feels too tight.
The saying comes from the idea that swinging something around needs a lot of space, and it jokingly uses a cat as the thing to swing around because cats are small enough to swing.
