you're not really showing age, they are still called sylvanians in europe and japan.
i collect certain families, mostly cats and odd animals, as they are expensive. i only buy full families as well, unless they are very rare. i have 3 cat families, a boar family, otter family, reindeer family, and two members of the very rare ermine family, which are my favorites. the otters have their canal boat house.
i have 2 boxes full of furniture from when i first found calicos locally, but now i'm a bit more picky.
