Hi shivvy....Oh this brings back memories..I have three cats old oldies now but let me tell you about Rastaz.15 years ago when I just had two cats , one day this black and white tom came in thecat flap he ate the other twos food then used the litter tray and he has been with us ever since.He was fine with my husband and myself and I could stroke him ect after making enquiries and contacting various cat rescue / c we decided that he could stay for good but because I had two other toms which were neutered we would do the same with Rastaz. So he was neutered .But what a change happened...was it because I took him to the vets, I do not know but his attitude to me was dramatic,he would not let me cuddle or stroke him, but he was fine with my hubby and still too this day he is still the same, whilst Im on my pc now hes giving me the dead eye lol.I love him too bits but the feelings are not returned.Its one of these cat things which we can never understand Im afraid. So you see shivvy its a question of what your cat wants to do not the other way round.They are a law unto themselves and thats what makes them so unique,,bless em.
