I cried my eyes out before taking her to the vet for the last time and she came up to me and licked my face and nibbled. She was an extremely affectionate cat.
I brought her back home so the other two could see/sniff her because I didn't want them to not understand that she just disappeared. One of them is definitely more concerned than the other.
Cats are pretty amazing creatures and while not all of them are super affectionate (my other two aren't) they seem to understand a lot more than we give them credit for. Mine always know and understand when I'm not feeling well and show it in their own ways. I will miss the hugs and cuddles from the one I said goodbye to... I needed those hugs and cuddles this week but the one that would give them wasn't with me anymore. Tough times.
I would encourage anyone to take the time with their animals and give them attention and love. You never know when a surprise may come and you have very little time to say goodbye.
