From the YouTube description
This is an automaton of a fur covered papier mache cat by Decamps of Paris Circa 1900. The film shows the restoration at the stage where all the parts have been repaired and the cat is tested prior to re-assembly.
Note the tail curl, it is a realistic action achieved with wooden balls wedged along a tapering spring within the tail, the cord pulls on the last ball only to curl it. This is a fragile part of the cat and is always broken in antique examples I have seen.
The restored cat is now for sale and can be seen at the Automatomania shop online shop.
