We took in a cat that we assumed was stray approx. 4 years ago. The cats owners liaised with our neighbour, and the cat was taken home a few times - each time however he returned to our flat. We were not ready for a pet, but the cat was pushy and desperate - we only started feeding him when we noticed the amount of time he would spend trying to come in. It was not long after contact with the owners had vanished did the cat have an accident which required veterinary attention; it was fairly affordable, but our neighbour gave some money toward the bill. 4 years on and the cat is living with us very comfortably. Our vet suggested we get the name changed in the chip to our family name/address - however we don't know how to go about it, and we're wondering if anyone can offer any advice? Thanks, Reg
