any advice - we are moving back to the uk shortly bringing our 2 adopted spanish cats with us,all passported , as they are from feral stock, they live outside, only coming in at meal times, my worries is, that when we arrive at our new home in the uk, it will be near on impossible to keep these cat inside (when they are kept in here is spain they go mad, jumping up at windows and making horrid noises) I am so worried that once out the door we will never see them again. any suggestions.
