Last night my old best friend whom we haven't seen in 11 years drove 13 hours up North for her brother and on her way her and her boyfriend and two youngest daughters stopped in for a visit. Well Mr. Daisy our 14 year old cat got up onto the table and started head bunting and nuzzeling my friend and her oldest daughter! He kept on going back and forth accross the table to the both of them hopping into my friends lap and rubbing his nose into her face! I have never ever seen Daisy react to anybody this way! It wa like he remembered them from 11 years ago! And he wa so happy to see them again! It was a beautiful reunion!
I think he DID remember their scent, and since she was your best friend, your cat was probably very familiar with her scent. He was greeting her as he would long lost family.
