Thread: Is tuna bad for cats or not?

I asked my vet this question a few years back when we wereresearching our diabetic cat's diet.
Apparently it is not the tuna which is the problem but themethods of preserving and canning the tuna for human consumption compared tothe methods used for pet use.
The vet suggested that some of the preservatives and additivescould upset the cats digestive system.
Again this was his opinion and he did not show us anymedical proof. Hope this helps.
