This looks like a mashup of that one yoyogi mori catgirl model with some other suit from booth. the hat looks like it might be from the same model. it won't be available anywhere for "yourself" and it won't have a name, it's something someone else threw together from parts.
if you look at yoyogi mori's booth page you will find the same cat there with different clothes, i think it still has the hat.
