MAC's Cat 6 x 200g

My two Bkh cats won't touch it... ended up throwing it all in the bin.

I bought the monoprotein turkey food, 24 cans. Unfortunately, the quality is inconsistent. Some cans are nice and smell good, and the cats eat them eagerly, but now there are only 6 cans left and they just stink, and one of my cats refuses to eat it at all. It's a shame. Now I don't know whether to keep buying it or not.
