I can understand how you feel about it, but Specs probably don't care whether he gets treats or not. However, you could try Royal Canin's S/O Sensitive - Fister loves them, so I give them as treats. Have you tried raw fish? Plaice, cod or shrimps, and Fister arrives in the kitchen in two seconds, even if he's fast asleep 3 rooms away. He will also eat grated Parmesan or boiled corn, and of course a slice of ham.
