I could not adore these kitties more, and it’s really hard not to keep them! Made in Japan by the Otagiri Mercantile Company (OMC) in the 1960s. One kitty is taller than the other, so may be depicting a mother/elder and teenaged kitten. Taller cat is 6”, smaller one is 5”. Both in flawless condition, with original maker’s stickers on the bottom and small round felt pads.
