What OS are you on? It is impossible for cat(1) on either Linux

It can when killed by a signal:
Does the shell report signal + 128 when a process is killed by a signal?
That's unfortunate, as 141 is a perfectly valid exit code (0 - 255).
But if that is the case, 141 is SIGPIPE.
Isn't that behavior pretty much required by POSIX? "The exit status of a
command that terminated because it received a signal shall be reported
as greater than 128."
