If you don't enter the tiger's den, you won't catch its cub. (Nothing ventured, nothing gained.)
This success is truly a hard-earned reward.
Standard kanji spelling for both senses; reading こし is the common reading for the 'baby tiger' sense, while the archaic 'bedpan' sense uses the gikun reading まる.
Archaic gikun reading used only for the 'bedpan' sense; cross-referenced with おまる.
The kanji 虎 (tiger) and 子 (child) literally mean 'tiger cub'. The archaic 'bedpan' sense with the gikun reading まる is of uncertain origin, possibly from a euphemistic or metaphorical use.
