He was not reclaimed, poor man. The pound just rang a rescue colleague, and I should be collecting him today. We are just arranging a foster; I am going to check with the vet on what his heart situation is. Very likely he just needs the usual tablets for cavalier hearts as they get older.
So he is now officially looking for his retirement home! I will consider a UK home as well, if I can arrange a homecheck and get vet references.
