Cat world time

=== Beginning ===
back in the old times cat world was thought to be a pocket dimension on earth but slowly with time the felis cati discovered more places and they found out that Cat World is an actual planet! cat world was originally discovered by a cat, but after technology got wiser they realized it was probably breeds of cats that lived in the ice age like a smilodon. the only thing that was actually unexplained was how did the smilodons evolve into cats? Smilodons/ancient cats evolved smaller and weaker through human interaction, but if those cats specifically tried to stay away from earth how did they evolve?
=== Differences ===
cat world's time is 325 years before earth (in terms of cakendar years), the first cat world event by a cat breed in that world was in 11,304 BC(C) [Before cat christ], this does not mean that they are in 9282 BC as of 2022, they are in 1697 as of 2022. which means that there is a 118625 days 16946.4 weeks or 3900 months between Earth 1 and Cat world. 
which meant that 2347 (The comverse collab year & PD Lore started) was 2022 in Cat World
