When I was a kid (a long long time ago) all you could buy was tuna packed in oil. At some point some genius said why not pack it in water. Tuna in a can has never been quite the same since. I bought this type in oil to feed a high protein treat to my cats on an occasion. My fussy kitties though seem to prefer the tuna in water version better. While this version is less expensive, the oil has to be drained off first before serving it, which is a messy, smelly process. With the tuna in water the cats also love to lick-up the water broth. No need to drain it. The water version tastes so good to me that it's almost too good to waste on cats. But I think in the future I will pay the extra cost for the packed in water version. Bumble Bee makes a premium product no matter which version you buy.
