Well I have know cats eat a few odd things - and one who was a people food thief who would hook food off plates with his paw when people weren't looking. He was particularly fond of younger children in this respect because even if adults managed to persuade the children not to feed him he could always hook food from their plates. He was supposed to be kept out of the room when people were eating but was an artist at hiding.
I think the 2 strangest tastes I have known were in my old tabby who I inherited when my mum died. He was fond of dried figs and would beg for the stalks to be given him rather than thrown out and also fried mushrooms. Never saw him eat raw mushrooms but if you fried them I reckon he would have polished off a whole portion if allowed. He never got more than a couple of fig stalks or small bits of fried mushroom and it did not seem to do him any harm as he got quite old before he got cancer.
