As for species I'd most like to see:
1.
Patagonian weasel- L. patagonicus (only Genus I haven’t seen)
2.
Nilgiri marten- M. gwatkinsii (would complete the Genus for me!)
3.
Mountain weasel- M. altaica (always saw it listed on zootierliste but never got a chance to visit Lithuania)
4.
Hairy-nosed otter- L. sumatrana (1 of 2 otters I haven’t seen, and the one that
@devilfish has me most jealous of)
