Thanks for that link, DM - I shall have that on standby! As to the grass, I did mention it some time ago in another thread. Kizzy will be able to go out in a few days time and will be able to eat her own grass if she wants to.
More strange behaviour this afternoon! We had a visit from the Memory Nurse and Kizzy kept coming in to the room we were having our discussion in - the kitchen, where else? - and SHOWING OFF - it was quite blatant! She even got up into the sink, just to say - hey look I'm being a naughty cat and my people aren't taking any notice of me!!!!
