I was thinking the same but - unusually for me - not rude enough to type it!
But seriously, even non-cat-lovers end up with half a dozen strays. Ours live wild somewhere nearby but appear at meal times. One is a massive 7kg and survived being slammed by a pickup truck. It escaped with only a broken pelvis. Another is looking very sick at present. Something wrong with its nose and eye. It's always fighting. I'd take it to the vet if I could catch it.
I guarantee that you'll bring one cat and end up with a lot more so ask yourself whether your cat might be happier living in the UK with a neighbour in the territory it knows. The feral cats and pine martens, here, can be quite vicious towards newcomers.
