Oh no! You missed out on stating this as 21.5 PETabytes!
I arrived at a similar order of magnitude via a different path. I suspect that almost all cute kitten pictures are just stored in a few (1-5?) locations, and assuming a power law such that maybe 1% of the world population kept 100-ish kitten pictures (almost all of which are by default cute), and maybe 5% more keep an average of 10-ish pictures. I’d estimate each picture to be on the order of a megabyte.

That yields around 36 Petabytes.
