This is interesting its a cat called Pogo whose job it is to test whether dogs are suitable to live with cats. Pogo interacts with the dogs to see whether they are going to be suitable for re-homing in a home where there are cats. At first Pogo is safe within the cat cage where he meets dogs of all sizes to gauge their reaction to him. If a dog pasts the first test and Pogo remains relaxed then he is let out of the cage to interact further with the dogs. Dogs that pass the second test are then deemed able to go to a home with cats. The Dogs Trust say that Pogo has lived with dogs all his life and is not put under stress during the encounters.
