Are the pouches different to the tins? Consistency wise and ingredients being different? Tried my cat on tinned Meowing Heads and this was the brand she hated the most. Her behaviour was very strange. She would tap that food out of the bowl (like I’ve seen her bat insects) with her paws and not eat it. We only tried two half tins (in different flavours) but it changed her behaviour temporarily and she acted like she was being punished and would run away from us at meal times. She became very suspicious of anything put in front of her for a while, even food she liked. It was an expensive bulk buy that went to the shelter.
