I dont know if you many of you know but about 20 months ago one of my cats called Gerry Scissor Paws went missing, we put all posters up etc but to no avail, about 3 months later we got a phone call from the vets saying they had Gerry (details from his chip) and I went and collected him, it turns out that he had wandered off and had been living with a lovely couple about a mile away, they didnt realise that he might be someones cat they thought he was a stray but their daughter said to take him to the vets to be scanned etc and that how we got him back. Anyway when we got him back we kept him in for 2 weeks going through the whole intro thing again etc etc and as soon as he got out he went straight back to the people that had been feeding him a mile away, this happened a few times so after much heartbreak we decided that Gerry should 'offically' become their cat and we changed the chip details etc etc, I do visit him occasionally and he is always really happy and his new owners love him to death. Things have moved on at our house as you know we now have Ripley, Gerry had also never seen Picalli and Ruby Red Pants as they were born after he left, but last night Gerry turned up at the window crying to come in our house, I phoned his new owners and although they were out to dinner they werent aware of any problems with Gerry and had indeed seen him about 2 hours before curled up on their bed. I didnt let Gerry in but I went out into the garden to see him and he was all hisses and growls but let me fuss him, as soon as another cat came anywhere near he went absolutely crazy. (even the cats he used to live with), I went in the house and waited for a while, went back outside and he had gone. This morning I get up and Gerry is there again doing exactly the same, wanting attention from me but being really vicious with the other cats. I dont know why he has come back, dont get me wrong I am pleased to see him, but he isnt our cat anymore and he really is upsetting the others. Maybe it is because he can smell another male cat (Ripley) on his old territory and he has come back to see ??, Ripley is due to be done at the end of this month maybe I should get him done earlier than that ? (he was born in May) but the vet did say he would rather do it nearer 6 months as he was so tiny, so my problem is I need to stop Gerry coming to the house. Any suggestions ??, it is all a bit surreal at the moment.
