A neighbour of mine found a cat five days ago who had wondered up to his farm- we are in a little village so not many cats wonder that far out. He unfortunately couldn't let her in his house as he has non cat friendly dogs, so she spent four days living in a make shift den in his garden. She is young, super skinny and full of ticks. She's been scanned for microchip but unfortunately doesn't seem to have one. I've taken her in and she is so so lovely- and so friendly so it's hard to believe she wasn't someone's pet, she also uses a litter tray. Is there anything I can do to find her owner? If not, can I get her chipped with my details and keep her?
