Thank you for your replies! I really appreciate your comments... they've heartened me. I must admit I almost froze when the vet told me about inactivity in fixed cats. I enjoy so much playing with Siro and seeing him jumping from one shelf to another ... Well, today is Friday so I have the whole weekend ahead to devote to my Sirocco and play with him, pet him and leave him alone (for there's always a moment His Royal Highness considers I'm already pestering him )

I'll keep updated (maybe in Cat Behaviour!) on how Siro goes on...

By the way, if we don't "meet" here in PetTalk (what I doubt very much ) this weekend, have a nice, nice time with you fur-babies!!
