This is an interesting story of a black cat in Poland who is described as angelic. His name is Radamenes. He went through a lot with a respiratory infection and we’re told he was at death’s door and about to be euthanised but was returned to good health at a veterinary centre where he has stayed to help other cats who are seriously ill by cuddling, massaging and even cleaning them or, as can be seen in the pictures, staying with them.
After he got better the staff at the veterinary center were surprised to see him hugging and cleaning other animals. He focuses his efforts on animals who have had serious operations. He is thought of as a full-time nurse at the clinic and is now the centre’s mascot.
