This is probably a really silly question. I have a poorly cat who is being treated by the vet and appears to be perking up a bit. I want to make him something tasty for supper as his appetite has been poor. I have bought some fresh fish but don't know if I should cook it first, or if I do cook it how should I do it? It's nice fish from Sainsbury's, a mixed selection to make fish pie. Normally all he eats is Felix and James Wellbeloved, never really been interested in human food. Please help!!
