Thanks to Blr & White Pegasus for the info & advice.
Perhaps she is just stressed. She just follows me round all the time, wanting to be fussed.
At first she seemed to be the one responding better, but now the other one seems more confident ~ even removing her bonnet & sneaking outside! I have managed to sort her out quickly, thankfully.
I'll remember about the citrus fruit, though, knowing these they would probably love it. cats aren't supposed to like water, but if they hear me running the taps for a wash, they'll be in the sink with me! ~ I'll remember to keep them away from it while they have stitches, though!
