Greyhound and cat sculpture

Very interesting metal sculpture of the cat trying to defend his pray against the Greyhound... finally not very interested.
Stunning sculpture quality close to 1900's Italian school. ( Antonio Amorgasti, Bugatti).
I cannot read signature. So, you are buying a question tag ! To be discovered.
(I really think it can be Amorgasti, but cannot assure that this is the signature)

Metal is patinated silver or pewter. (White metal. Not spelter). Plaster underneath. Wood basis.
Circa 1900-1920. Excellent condition.
