Animals animatronics

The saber tooth cat made by the people at Jim Henson's creatures shop

After looking at my dog (olli) i decided to look at how people have made animals before looking at the technical side to it all and the muscle structure because they are different to the humans. Also that cats use for legs to walk on same as dogs humans don't. The only problem is that cats have a certain walk and movement about them which i don't think the saber tooth cat got in the costume. It looks too much like a costume than a realistic cat. This is why i looked at the raptors from Jurassic park they have humans in them but look very bird like and this is what you expect raptor to move like. The menacing movements and quick jerky head actions.
