in case if anyone else find feline smudging too much, i've found a better replacement. the prestige total intensity eyeliner in deepest black glides on even more smoothly than feline and is actually darker (yes! it's possible) it stayed on my lid better than ud 24/7 and feline. oh, and it cost about 1/3!
i gave away my feline, so i cannot compare them directly, but here's how it compares to ud zero and MUFE aqua eyes (0L)
L to R: prestige, Orpheus kohl power, UD zero, MUFE, prestige again
i included orpheus just because it has similar texture to feline
lightly swiped
went back and forth a few times (except the leftmost) and added a liquid eyeliner(also prestige) on the right
smudged with my fingers (went extra hard on prestige + MUFE and they didn't budge)
rinsed & rubbed under water for a good minute or two
washed & rubbed with a mild hand soap. the only one left was the urban decay. probably because there's so much was in it (i don't like the waxiness. i find some of the colors won't glide on smoothly because of it)
so yah, i don't think i'll be buying feline this year
