Thanks Nicola and Dawn for your advice!! Actually I was also thinking if it is possible for the 12 year old girl to participate in some volunteer work once the summer break kicks in, I believe if this can be done, it would be the best training for her. She, I am quite sure will have to take the initiative of the cat care in general if they are going to have one, needs to know every aspect of the commitment, not just the fun stuff and must be sure she can cope with it on a daily basis. If not, they need to work with Oliver but the boy tend to get overzealous with our cat every time they come over, and Oliver is less enthused about this idea for sure. But then again, the boy needs to learn to respect the need or a cat and learn more of the behaviour/tendency of the cats as well, so it is probably beneficial for him to learn to restrain himself rather than chasing relentlessly around the cat and tormenting him.
But really I believe the one who needs the heaviest dose of education is the mother. We have still a few months at least to work on and decide, so we do all we can and see how it goes... and I will keep you posted. Thanks again!!
BTW Dawn, I guess it is a bit of a mediterranean tendency about the attitude towards cats in some rural part of Italy. When I was living in Andalucia, Spain (it was early 90's), many Spaniards in the region didn't consider cats as "house pets" either. But of course it has changed in modern times and places. The word you are talking about is "schifo", yep it is the equivalent of gross, disgusting, yucky etc. etc., widely used colloquial expression! And the girl needs to get her taste of cleaning the litter tray definitely, as I am pretty sure her first reaction will be "ewww, che schifoooo!!" She needs to overcome that shock and that will be the starting point!!
