TIL - Apparently, Northwest native languages picked up their words for house cat from kitty-calling sounds:
Nimiipuutimt (Nez Perce): picpic ('c' goes 'ts')
Lushootseed (Snoqualmie): pišpiš
Chinook Wawa: puss'-puss

Contrast Shoshone languages, which seem to have simply grabbed the English: kedi, kiidi, kaattu

If you like this sort of thing, here's Brown Bear, Brown Bear, What Do You See? in Nimiipuutimt.
