Same deal with my two cats when they come back from the groomer. They went to the grommer together, they see other getting fur cut, went home together, still don't recognize each other 😑
I have two cats. Once I had a 4 houseguests staying in the living room for a week. After they left my one cat (the dumb one, obviously) didn't recognize her sister anymore. At no point did any cat leave the premises.

We have two cats and our name for this phenomenon is “other brother”. As in, each cat is convinced their brother has been replaced with a doppelganger that isn’t quite right. Hence, “other brother”.
