Hi all - my 11 year old cat has started being very affectionate over the past two weeks. She's never been aloof or standoffish, she's always been happy to sit on a lap and have a cuddle, but now she is pestering me to stroke her and rubbing her face against any bit of me she can reach, and purring at the mere sight of me. As far as I can tell she is okay in all other regards, and drinking enough in the hot weather - can anyone offer any wisdom, please? TIA
