Hi: #2 is scavo glass, which was developed in Murano to imitate the look of Roman glass that had lain buried for many years. Barbini and Cenedese did a lot of it, but this piece doesn't remind of anythign I've seen from them. I seem to remember someone, Ivo, I think, saying that Egypt produced a great of scavo now. You might want to search threads under scavo.
Is the surface of the cat mottled, as if it's been partly eaten away by acid? If so, it's a corroso finish. Barbini used corroso and also did animals, including cats very much like this one. I'm not certain, particulalry as Max thinks it might be Nason, but I'll look in a few books. You might try googling Barbini cats and see what emerges.
