probably after effects, although it can be done in several others quite easily

features of the cat are motion tracked, then you link various layers to that motion tracked data

[smok3]

no need for motion tracking here, probably any nle can do that, just some keyframes and some layers.

And you need to do it once for some 2 seconds, then reuse the "template" for all variations ...
