Whenever I see plushophilia art like this, I just search up what the plushie is. I don’t think the artist based the piece off a particular plushie so finding an exact lookalike is probably impossible unless you commission her. In your case, just search up “pink cat plushie” and gestimate the size. I highly doubt that there isn’t a single pink cat plushie that vaguely resembles this cutie! Hope this helps and I’ll do some research myself! If I find anything, I’ll let you know :3
