That depends entirely on your operating system and disk space.

Squid is write appending to them constantly. If your OS does append in
an efficient way there is theoretically no reason why file size should
matter until disk runs out. If it is doing something stupid like seeking
to the end all the time it could cripple Squid, since caching at high
speed does the same write appending on almost a per-packet basis.

NP: cache.log is where important administrative messages are logged. If
it gets very large, outside of special debugging administration, there
are serious problems needing to be fixed in your installation.
