do cats remember much?
Oh they remember!
Have had a long relationship (13 years) with a neighbour/friends cat. They moved and so did the cat. Didn't see them for four years. Went to visit and the cat was sunbathing on roof heard my voice and came running to greet me partly delighted, partly annoyed. Where have you been? It was like two old cats in an urban Serengeti acknowledging each other's survival.
