I was under the impression shrews were obligate insectivores.

My memory of mice suggests a 1cm mesh will stop them, but a 1cm high
slot wouldn't even slow them down.

Shrews are omnivores, eating insects, spiders, worms, frogs, mice and
some plants and seeds. The main diet of a shrew is carnivorous, with
shrews preferring a meal of millipedes, earthworms, or birds rather than
nuts and seeds.
