I'd like to add a comment on the cats in regards to Time Bastards ironclad fan-fiction "no way there's duplicates" standpoint and it's subsequent "un-realistic"/"unreasonable" restrictions on possibilities, (lol). Just a comment, because it is very difficult to take a side here.
I insist they could definitely be the same cats from different timelines based on the fact that timeline counterparts can be incorporated onto the same team in CronoCross. The only way Time Bastard holds up is if the cats are Chrono's and his new timeline selves that disappeared for every timeline correction were exactly and directly responsible for them being anywhere in the vicinity.
I posted in "A late late late late Time Bastard debunk" that Chrono himself is the Chrono Trigger. IF the effects of his time travelling don't ACTUALLY occur until he is back through the portal to the corresponding change time, then there could conceivably be a time allowing for error during which the cats could take it upon themselves to first, go through the time gate to a past or future time awaiting the effect of Chrono's actions, and then, return back through a time gate to where they build up in-game, then yes, they are all the same cat.
Sadly, I further posted how the whole vests and plates thing discredits MY explanation of the debunking, but the vests and plates can't move on their own, sooooo, totally different fanfic right here ^^ ^^ ^^ ^^ ^^ ^^ ^^
