Fast forward a few months to winter. The cat has been appearing less frequently, but looking more ragged each time, as if it doesn't have adequate shelter. After a long stretch where you start to wonder if the cat is dead, it appears at your doorstep. It's ears look frostbitten, and the rest of its body looks like it has seen some rough times.
On a scale of one to 10 - one being alright, 10 being "you're the worst! A blight on both of your houses!" - how bad would it be to take the cat to the vet, get it all fixed up and keep it as your own pet?
