My 8 yr old White cat - Harvey - has become very vocal. He yells when he comes in, "I've been out mum, and now I'm back, have you missed me?" Well that's what I think he's saying. It's not a meow but a full on yowl. I did wonder if he was distressed about something, but I don't think so now. I'm down to two cats now, poor little Jess became very poorly and had to be pts aged 17 a few weeks ago. We all miss her, in fact both Harvey and Carrie wandered round looking for her for days and Harvey doesn't understand why he's now allowed upstairs, previously that was Jess's territory because they didn't get on at all.
