It's hard to tell exactly what it is like with just one photo, taken from just one angle.
It does look a little like cat figurines made by an american company called Mosser, and I've searched under images to try to find an opalescent one, without luck.
You could try searching yourself, and see if what comes up looks the same as your cat.
(you might have to insist your search engine puts the double ss in the middle, it tends to default to Moser, a completely different glass company.)
I would personally be suspicious of a label reading "Murano glass" on any pressed piece.
Welcome to the board.
