We went up to the local Cat's Protection League shelter just before Christmas, to take some food up to them and see how Barney was getting on. He wasn't there, because he had just been rehomed with a family about 15 miles from here, who have sons aged 4 and 7.
They told me that he very quickly turned into a loving cat, who enjoyed sitting on the table and getting fuss. I suspected he would, but was very pleased everything had worked out and surprised it had taken them less than two months to get him healthy, used to being with people again and to home him. One of the volunteers commented that it's cats like Barney that make the job really worthwhile.
I still feel a bit guilty that I couldn't look after him myself, but I'm pleased everything worked out.
