Yes. Just ask my cats. I was gifted with the secrets of removing tuna from a can. My genius has even won me the coveted Hairball Award on several occasions.
My large cat wants to be hand fed. The vet told him he has arthritis in his back end so he milks it for all he can get. He reads all the labels. If it says fish he loves it. If it says chicken - even with fish - he wants nothing to do with it... and this is before a can is opened.
I know all about that. My cats start howling for fish at 5:30 every morning (their breakfast isn't until 9:30 after I've gone for my morning walk). And boy are they loud!
