Yes same here with the food, Teddy generally has Fe lix sachets but sooo many different varieties now. Beef with carrot, another with courgette, saith with salmon etc etc. Yes licks all the gravy or jelly off and leave the dried lumps behind, then you add cat soup and then he does the same. The remains go in the bird box which my wife puts out late in the evening usually encountering the resident hedgehog and some stray cat and all is wolfed down!
Tried all the cheaper ones and generally will eat first sachet then no more. Yes and goes berserk for prawns and tongue!
Thinking back to the seventies we had katkins, kit e kat or whiskas in tins and that was it. Plus we always gave our cats milk to drink but now it's harmful so just water!!
