I currently feed 6 brands, 8 flavours (excluding homecooked) and rotate with each can. Even if there is any problem with a certain brand, he won't get into too much of a problem with just one to two cans per week. I am gonna take away TOTW canned cos the 1st ingredient is salmon and the smell and look, seemed gross to me. I will keep adding new variety if I can find any that ET will eat and within my budget. Natural Balance and Nature's Variety is way too expensive here, so I won't consider.
Even though ET is getting finicky, but I still managed to get him to eat those that he won't completely reject by adding toppings. And like cinderflower, I do open another can before one can finishes, so ET gets 2 different flavours/brands in a day. ET is a small eater, so sometimes one can will take 3 days to finish.
Brands like Evo 95%, Wellness regular, Addiction (pate style), Holistic Select, there is simply no way I can get him to eat, even when I just add a tsp hidden with his usual food. He can smell it and simply refused the whole plate. Anyway, since he already has a couple other brand, so I won't force this on him.
