Lol we have a cross-species fix here too. There's a tiny house rodent that eats infant mice, is much slower-reproducing, and prefers cat-free environs. We all voted to let em stay. The mouser loves to catch and display then but they don't taste good enough to eat... so they serve as mute periodic memos on the rodent situation.

THAT reminds me-- it's that time of year to invite the mousers into the unheated storage rooms though-- I'll have to remind HardI it's time to let the cat hair back into his weight room, which connects with the prey zone.
